Answer:

  (x, y) = (5.76, 1 5/7)

Explanation:

The location of the centroid in the x-direction is the ratio of the first moment of area about the y-axis to the total area. Similarly, the y-coordinate of the centroid is the first moment of area about the x-axis, divided by the area.

For the moment about the y-axis, we can define a differential of area as ...

  dA = (y2 -y1)dx

where y2 = √(x/k2) and y1 = k1·x^3

The distance of that area from the y-axis is simply x.

So, the x-coordinate of the centroid is ...

  \(\displaystyle c_x=\frac{a_x}{a}=\frac{\int{x\cdot dA}}{\int{dA}}\\\\a_x=\int_0^{12}{x(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{5k_2^{1/2}}\cdot12^{5/2}-\frac{k_1}{5}12^5\\\\a=\int_0^{12}{(k_2^{-1/2}\cdot x^{1/2}-k_1x^3)}\,dx=\frac{2}{3k_2^{1/2}}\cdot12^{3/2}-\frac{k_1}{4}12^4\\\)

For k1 = 4/12^3 and k2=12/4^2, these evaluate to ...

  \(a_x=115.2\\a=20\\c_x=5.76\)

The y-coordinate of the centroid requires we find the distance of the differential of area from the x-axis. We can use (y2 +y1)/2 for that purpose. Then the y-coordinate is ...

  \(\displaystyle c_y=\frac{a_y}{a}\\\\a_y=\int_0^{12}{(\frac{y_2+y_1}{2}(y_2-y_1))}\,dx=\frac{1}{2}\int_0^{12}{(\frac{x}{k_2}-(k_1x^3)^2)}\,dx\\\\a_y=\frac{12^2}{4k_2}-\frac{k_1^212^7}{14}=\frac{240}{7}\\\\c_y=\frac{12}{7}\approx1.7143\)

The centroid of the shaded area is ...

Answer:

The answers are in the explanation. The pH is 5.91

Explanation:

The CH3NH2 reacts with HCl as follows:

CH3NH2 + HCl → CH3NH3⁺ + Cl⁻

When 200mL of HCl are added, the moles of CH3NH2 and HCl are reacting completely producing CH3NH3+ and Cl-. That means the species present are:

no H+. All reacted

yes H2O. Because the water is present in the solutions of HCl and CH3NH2

yes Cl-. Is a product of the reaction

Yes CH3NH2. Is consumed in the reaction but comes from the equilibrium of CH3NH3+

yes CH3NH3+. Is the other product of the reaction. MAJOR SPECIES

When 300.00mL of HCl are added, 100mL are in excess:

yes H+. Is in excess: H+ + Cl- = HCl in water. MAJOR SPECIES. Determine the pH of the solution.

yes H2O. Is present because the reactants are diluted.  

yes Cl-. Is a product of reaction and comes from HCl.

Yes CH3NH2. The reactant is over but comes from the equilibrium of CH3NH3+

yes no CH3NH3+. Yes. Is a product and remains despite HCl is in excess.

To find the pH:

At equivalence point the ion that determines pH is CH3NH3+. Its concentration is:

0.100L * (0.200mol/L) = 0.0200 moles / 0.300L = 0.0667M CH3NH3+

The equilibrium of CH3NH3+ is:

Ka = Kw/kb = 1x10-14/4.4x10-4 = 2.273x10-11 = [H+] [CH3NH2] / [CH3NH3+]

As both [H+] [CH3NH2] comes from the same equilibrium:

[H+] =  [CH3NH2] = X

2.273x10-11 = [X] [X] / [0.0667M]

1.5159x10-12 = X²

X = 1.23x10-6M = [H+]

As pH = -log [H+]

pH = 5.91

The pH at the equivalent point for this titration is "5.91".

\(CH_3NH_2 = 0.200\ M\\\\ \text{volume} = 100.0\ mL = 0.100\ L\\\\HCl = 0.100\ M\\\\\)

We must now quantify the pH well at the equivalence point.

We know that even at the point of equivalence, moles of acid and moles of the base are equivalent. As such, first, we must calculate the number of moles of the given base.

Calculating the Moles in \(CH_3NH_2 = 0.200\ M \times 0.100\ L = 0.0200\ moles\)

Calculating the Moles in \(HCl = 0.0200 \ moles\)

Calculating the volume of \(HCl\):

\(\to \text{Molarity} = \frac{ \text{moles}}{\text{volume \ (L)}} \\\\\to \text{Volume} = \frac{\text{moles}}{\text{molarity}}\\\\\)

                \(= \frac{0.0200 \ moles}{ 0.100\ M}\\\\= 0.200 \ L\\\\= 200 \ mL\\\\\)

Calculating the reaction among the acid and base:

\(CH_3NH_2 + HCl \longrightarrow CH_3NH_3^{+} + Cl^-\)

\(0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200\)

Therefore the conjugate acid of the bases exists at the standard solution.

Then we must calculate the new molar mass of \(CH_3NH_3^+\).

Total volume\(= 100 + 200 = 300\ mL = 0.300\ L\)

\([CH_3NH_3^+] = \frac{0.0200\ mole}{ 0.300\ L}= 0.0667\ M\)

Using the ICE table

\(CH_3NH_3^+ + H_2O \longrightarrow CH_3NH_2 + H_3O^+\)

\(I \ \ \ \ \ \ \ \ \ \ 0.0667 \ \ \ \ \ \ \ \ \ 0\ \ \ \ \ \ \ \ \ 0\\\\C\ \ \ \ \ \ \ \ -x\ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ +x\\\\E \ \ \ \ \ \ \ \ \ \ \ \ 0.0667-x \ \ \ \ \ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ \ \ \ \+x\\\\\to Ka = \frac{[CH_3NH_2] [H_3O^+] }{[CH_3NH_3^+]}\)

Calculating \(K_a\) from \(K_b\)

\(\to K_a \times K_b = 1\times 10^{-14}\\\\\to K_a = \frac{1\times 10^{-14}}{4.4\times 10^{-4}} = 2.27\times 10^{-11}\\\\\)

                           \(= 2.27\times 10^{-11} \\\\= x\times \frac{x}{(0.0667-x)}\)

The x in the 0.0667-x can be ignored since the Ka value is just too small and it also does not follow the five percent criteria.

\(\to 2.27 \times 10^{-11} \times 0.0667 = x_2\\\\\to x_2 = 1.515\times 10^{-12}\\\\\to x = 1.23\times 10^{-6}\ M\\\\\to [H_3O^+] = x = 1.23\times 10^{-6}\ M\\\\\)

We have the formula to calculate pH.

\(\to pH = - \log [H_3O^+] = - \log 1.23\times 10^{-6}\ M= 5.91\)

The pH at the equivalent point for this titration is "5.91".

A literature review is a comprehensive analysis of literature or research publications that relate to a specific topic or question. In this case, we are reviewing published research and literature on the importance of lubrication in rolling-contact and journal bearings.

Lubrication plays a crucial role in the functioning of rolling-contact and journal bearings. Some of the essential functions of lubrication include reducing friction between surfaces in contact, minimizing heat generated by friction and reducing the chances of overheating, providing a layer of protection against corrosion and rust, and acting as a coolant for bearings that generate a lot of heat.

Bearing lubricants should have specific physical and chemical characteristics depending on the application. For instance, transmission fluids should have a high viscosity to provide the necessary lubrication and protect the gears from wear and tear. They should also have excellent thermal stability to perform effectively at high temperatures and prevent the formation of sludge and other deposits.

Engine oils should have excellent anti-wear additives that reduce wear and tear on engine components. They should also have good detergency to keep the engine clean and prevent the formation of deposits. Additionally, they should have low volatility to prevent excessive oil consumption and reduce emissions.

For marine or offshore applications, lubricants should have good water separation properties to prevent the formation of rust and other deposits. They should also have good rust protection properties and be biodegradable to minimize the impact on the environment.

In summary, lubrication is vital for the efficient and safe functioning of rolling-contact and journal bearings. Lubricants should have specific characteristics depending on the application, and a literature review can provide valuable insights into the importance of lubrication in these bearings.

Answer:

a) the output voltage is 50 V

b)

- the average inductor current is 10 A

- the maximum inductor current is 13 A

- the maximum inductor current is 7 A

c) the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components is 4 A

Explanation:

Given the data in the question;

a) the output voltage

V₀ = V\(_s\)/( 1 - D )

given that; V\(_s\) = 20 V, D = 0.6

we substitute

V₀ = 20 / ( 1 - 0.6 )

V₀ = 20 / 0.4

V₀ = 50 V

Therefore, the output voltage is 50 V

b)

- the average inductor current

\(I_L\) = V\(_s\) / ( 1 - D )²R

given that R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6

we substitute

\(I_L\) = 20 / (( 1 - 0.6 )² × 12.5)

\(I_L\) = 20 / (( 0.4)² × 12.5)

\(I_L\) = 20 / ( 0.16 × 12.5 )

\(I_L\) = 20 / 2

\(I_L\) = 10 A

Therefore, the average inductor current is 10 A

- the maximum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] + [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmax\) = [20 / (( 1 - 0.6 )² × 12.5)] + [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmax\) = [20 / 2 ] + [ 60 / 20 ]    

\(I_{Lmax\) = 10 + 3

\(I_{Lmax\) = 13 A

Therefore, the maximum inductor current is 13 A

- The minimum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] - [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmin\) = [20 / (( 1 - 0.6 )² × 12.5)] - [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmin\) = [20 / 2 ] -[ 60 / 20 ]    

\(I_{Lmin\) = 10 - 3

\(I_{Lmin\)  = 7 A

Therefore, the maximum inductor current is 7 A

c)  the output voltage ripple

ΔV₀/V₀ = D/RCf

given that; R = 12.5 Ω, C = 40 μF = 40 × 10⁻⁶ F, D = 0.6, f = 200 Khz = 2 × 10⁵ Hz

we substitute

ΔV₀/V₀ = 0.6 / (12.5 × (40 × 10⁻⁶) × (2 × 10⁵) )

ΔV₀/V₀ = 0.6 / 100

ΔV₀/V₀ = 0.006 or 0.6%V₀

Therefore, the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components;

under ideal components; diode current = output current

hence the diode current will be;

\(I_D\) = V₀/R

as V₀ = 50 V and R = 12.5 Ω

we substitute

\(I_D\) = 50 / 12.5

\(I_D\) = 4 A

Therefore, the average current in the diode under ideal components is 4 A

In descending gliding flight, an airplane experiences several forces and moments. The derived equation is ΣFx = W cos(γ + α) - L = 0.

To derive the equations of motion, let's start by drawing a free body diagram.

The diagram includes the following elements:

The aircraft, represented by a body with the longitudinal and vertical axes.

A coordinate system with an x-axis (horizontal) and a y-axis (vertical) that are fixed with respect to the Earth.

The velocity vector, which makes an angle φ (phi) below the horizon.

The weight force acting vertically downward.

The lift force perpendicular to the velocity vector.

The drag force opposite to the velocity vector.

The thrust force, assumed to be zero for gliding flight.

Now, let's consider the forces acting on the aircraft. The weight force can be decomposed into components: Wx in the x-direction and Wy in the y-direction.

The lift force can be decomposed into components: Lx in the x-direction and Ly in the y-direction.

The drag force can be decomposed into components: Dx in the x-direction and Dy in the y-direction.

In the vertical plane, the equations of motion are given by:

ΣFy = Wy + Ly - Dy - W = 0, where W is the weight of the aircraft.

ΣFx = Wx + Lx - Dx = 0.

We can rewrite these equations using trigonometric relationships:

ΣFy = W sin(γ + α) - D - W = 0, where γ is the glide path angle (equal to -φ in this case).

ΣFx = W cos(γ + α) - L = 0.

Since the aircraft is in gliding flight, the thrust force T is assumed to be zero.

These equations of motion have only one degree of freedom because the aircraft's motion is constrained to the vertical plane.

Explanation:

Given that a transparent film is to be bonded onto the top surface of a solid plate inside a heated chamber. For the bond to cure properly, a temperature of 70°C is to be maintained at the bond, between the film and the solid plate. The transparent film has a thickness of 1 mm and thermal conductivity of 0.05 W/m·K, while the solid plate is 13 mm thick and has a thermal conductivity of 1.2 W/m·K. Inside the heated chamber, the convection heat transfer coefficient is 70 W/m2·K. If the bottom surface of the solid plate is maintained at 52°C.

To determine the temperature inside the heated Chamber, let us first calculate the heat transfer rate per unit area through the plate by using the formula

Heat transfer rate R = k( Tb - T2)/L

Where

k = 1.2 W/mA.K

Tb = 70 degree

T2 = 52 degree

L = 13mm = 13/1000 = 0.013m

substitute all the parameters into the formula above.

R = 1.2 x ( 70 - 52 )/ 0.013

R = 1.2 x (18/0.013)

R = 1661. 5 W/m^2

the surface temperature of the transparent film will be

Ts = Tb + (RLf/Kf)

Ts = 70 + (1661.5 x 0.001)/0.05

Ts = 70 + (1.6615)/0.05

Ts = 70 + 33.23

Ts = 103.23 degree centigrade

the temperature inside the heated Chamber will be calculated by using the formula

Ti = Ts + (R/h)

Ti = 103.23 + (1661.5/70)

Ti = 103.23 + 23.74

Ti = 126.97 degree centigrade

In the given scenario, the flow is pressure-driven, which means that the flow rate is determined by the pressure difference between the two ends of the coaxial cylinders. Additionally, the flow is confined to the annular region between the cylinders, with glycerin as the working fluid at a temperature of 20°C.

The pressure-driven flow of glycerin at 20°C in the annular region between two coaxial cylinders with an inner radius r1 can be described by the Hagen-Poiseuille equation. This equation relates the flow rate of a viscous fluid in a cylindrical pipe to the pressure difference across the pipe and the properties of the fluid and the pipe.
The Hagen-Poiseuille equation states that the flow rate (Q) is directly proportional to the pressure difference (∆P), the fourth power of the radius (r^4), and inversely proportional to the viscosity (μ) and the length of the pipe (L).
Mathematically, it can be expressed as:
Q = (π/8) * (∆P) * (r1^4 - r2^4) / (μ * L)
where r2 is the outer radius of the annular region.

If the steam is incompressible, it means that its specific volume remains constant throughout the process. In this case, the enthalpy per kilogram of steam leaving the nozzle will also remain constant.

Given that the specific enthalpy of the steam at station A is 3278 kJ/kg and the velocity at station A is 20 m/s, we can calculate the enthalpy per kilogram of steam leaving the nozzle.

The enthalpy per kilogram of steam leaving the nozzle can be determined using the specific enthalpy equation:

h2 = h1 + (V1^2 - V2^2)/2

Where:

h1 = specific enthalpy at station A

h2 = specific enthalpy at the exit of the nozzle

V1 = velocity at station A

V2 = velocity at the exit of the nozzle

Since the steam is incompressible, the specific volume remains constant. Therefore, the velocity at the exit of the nozzle, V2, can be calculated using the equation:

V2 = V1 * (A1/A2)^0.5

Where:

A1 = cross-sectional area at station A

A2 = cross-sectional area at the exit of the nozzle

Since the exit area of the nozzle is adiabatic, the cross-sectional area at the exit remains the same as the cross-sectional area at station A (A1 = A2).

Substituting the given values into the equations, we can calculate the enthalpy per kilogram of steam leaving the nozzle:

V2 = V1 * (A1/A2)^0.5

V2 = 20 m/s * (1/1)^0.5

V2 = 20 m/s

h2 = h1 + (V1^2 - V2^2)/2

h2 = 3278 kJ/kg + (20^2 - 20^2)/2

h2 = 3278 kJ/kg

Therefore, the enthalpy per kilogram of steam leaving the nozzle is 3278 kJ/kg, assuming the steam is incompressible.

Vladimir Lenin's New Economic Policy (NEP), introduced in 1921, was a political compromise primarily aimed at satisfying the concerns of the peasantry and various social groups impacted by the War Communism policies.

The NEP was designed to foster economic recovery and alleviate widespread food shortages, as well as to counter growing dissatisfaction among the populace.

Under War Communism, the Bolshevik government had nationalized industries, requisitioned grain from peasants, and suppressed private trade. This resulted in food shortages, declining agricultural production, and economic stagnation, leading to discontent among the peasants, workers, and the general population.

The NEP sought to address these issues by implementing a series of market-oriented reforms that partially restored elements of capitalism. Key aspects of the NEP included permitting private ownership of small businesses, allowing peasants to sell their surplus products on the open market, and introducing a tax-in-kind system that replaced the forced requisitioning of grain.

By adopting the NEP, Lenin sought to achieve a delicate balance between maintaining control over the economy and satisfying the needs and demands of various social groups. The policy was intended as a temporary measure to ensure the survival of the socialist state and gain support from the peasantry, who constituted a majority of Russia's population. The NEP successfully improved living conditions and stabilized the economy for a time but was eventually replaced by Stalin's Five-Year Plans in the late 1920s.
