The optimal production mix for the company is 30 chairs and 60 desks, resulting in a profit of $4200.

To determine the optimal production mix for the furniture company, we need to find the combination of chairs and desks that maximizes the company's profit. Let's solve this problem graphically.

Let's assume x represents the number of chairs produced and y represents the number of desks produced.

Constraints:

1. Sawing department: 120x + 80y ≤ 120 chairs or 80 desks

2. Chair assembly department: x ≤ 60 chairs

3. Desk assembly department: y ≤ 60 desks

4. Paint department: 90x + 110y ≤ 90 chairs or 110 desks

The objective is to maximize profit, which can be represented as P = 20x + 50y.

We plot the feasible region formed by the constraints on a graph and then identify the corner points of the region. The corner point that maximizes the profit is the optimal production mix.

Solving the equations and graphing the feasible region, we find that the corner points are:

A(0, 0), B(0, 60), C(30, 60), D(60, 30), E(60, 0)

Evaluating the profit function at these corner points, we find:

A(0, 0): P = 0

B(0, 60): P = 60 * $50 = $3000

C(30, 60): P = (30 * $20) + (60 * $50) = $4200

D(60, 30): P = (60 * $20) + (30 * $50) = $3300

E(60, 0): P = 60 * $20 = $1200

Therefore, the optimal production mix for the company is 30 chairs and 60 desks, resulting in a profit of $4200.

The net positive suction head (NPSH) is define as the difference between the total head on the suction side and the pressure head of liquid vapor, velocity, and static. Therefore, the correct option is D- All of the above.

Net positive suction head (NPSH) is a pump industry term that describes the suction side of a centrifugal pump. It is the absolute pressure head, less the vapor pressure, at the pump suction port. The NPSH is defined as the total suction head in feet of liquid absolute, less the vapor pressure in feet absolute. It's also the amount of fluid that a pump needs to function properly. This head must be considered for any pump that is pumping a liquid, and it must be greater than the pump's NPSHr (net positive suction head requirement). It's a measure of the pressure required to keep a fluid from boiling. The most common cause of cavitation is the lack of NPSH. Cavitation is a problem because it generates noise, vibration, and damage to pumps, seals, and impellers.

A centrifugal pump's efficiency and capacity are both affected by NPSHA. Pumps can have severe damage or not function at all if the NPSHA is not enough for the NPSHR (required net positive suction head) of the pump being used.

Answer:

the percentage of light that gets through this combination is 9.38

Explanation:

Given the data in the question;

Let us represent the incident unpolarized light with \(I_0\).

So, the amount of light intensity passing through the first polarizer will be;

\(I_1\) = \(I_0\) / 2 ------ let this be equation 1

An the amount of light intensity passing through the second polarizer will be;

\(I_2\) = \(I_1\)cos²θ

given that; the second one has its transmission axis at 30°

so, we substitute;

\(I_2\) = \(I_1\) × cos²( 30° )

\(I_2\) = \(I_1\) × 0.75

\(I_2\) = 0.75\(I_1\)

from equation; \(I_1\) = \(I_0\) / 2

\(I_2\) = 0.75( \(I_0\) / 2 )

\(I_2\) = 0.375\(I_0\) .

Now, the amount of light intensity passing through the third polarizer will be;

\(I_3\) = \(I_2\)cos² ( 90° - 30° )

\(I_3\) = \(I_2\) × cos²( 60° )

\(I_3\) = \(I_2\)  × 0.25

we substitute

\(I_3\) = 0.375\(I_0\)  × 0.25

\(I_3\) = 0.09375\(I_0\)

∴ \(I_3\)/\(I_0\) × 100 = 0.09375 × 100

⇒ 9.38%

Therefore, the percentage of light that gets through this combination is 9.38

Since the width of a frictional material on a multiple disc clutch is (r₂ - r₁)  the inside diameter of the multiple disc clutch is 81 mm

Let

Given that the width of a frictional material on a multiple disc clutch is (r₂ - r₁) and is equal to half of the maximum radius (R), we have that

w = r₂ - r₁  (1)and

w = R/2 (2)

Since R = r₂

w = r₂/2   (3)

Equating equations (1) and (3), we have

r₂ - r₁ = r₂/2  

r₁ = r₂ - r₂/2  

r₁ = r₂/2  

Since the maximum diameter d₂ of the coupling is not to exceed 162 mm, we have that

r₂ = d₂/2

So, r₁ = r₂/2  

r₁ = d₂/4

r₁ = 162 mm/4  

r₁ = 40.5 mm

Now the inside diameter d₁ = 2r₁

So, d₁ = 2 × 40.5 mm

= 81 mm

As a result, 22.7 metres is the greatest distance between the transmitter and receiver at which the received SNR is 20 dB.

To determine the received power Pr at a distance d from the transmitter with a transmit power of Pt, we can use the following formula: Pr = Pt - PL(d), where PL(d) is equal to K + 10 gamma log10(d/d0).

The following formula can be used to determine the farthest distance dmax at which the received signal-to-noise power ratio (SNR) is 20 dB:

Pr / N0 = SNR

SNR being equal to 20 dB, the formula becomes:

Pr=SNR*N0 = 10

(SNR/10) * N0

In the equation above, we may substitute the equations for Pr and PL(d) to obtain:

Pt-K-Gamma*Log10(d/d0) = 10(SNR/10)*N0

When we solve for d, we obtain: d = d0 * 10

(10 * gamma) / ((Pt - K - SNR * 10 * log10(N0) - 10 * gamma * log10(d0)))

d = 1 * 10^

Explanation:

To determine whether you should increase or decrease the length of the pendulum of your grandfather clock, you need to understand the relationship between pendulum length and time period.

The time period of a pendulum is the time it takes for one complete oscillation (back and forth). It can be calculated using the formula:

T = 2π√(L/g)

Where:

T is the time period,

L is the length of the pendulum, and

g is the acceleration due to gravity.

If the clock gains 21 seconds per day, it means that the time period is longer than the desired value. To decrease the time period, you need to decrease the pendulum length.

To find out by how much you should change the pendulum length, you can use the following steps:

Calculate the current time period (T) using the given length (L = 0.9930 m) and the known acceleration due to gravity (g = 9.8 m/s^2).

Determine the desired time period based on the clock's accuracy (24 hours = 86400 seconds).

Find the difference between the current time period and the desired time period.

Adjust the pendulum length in the appropriate direction (decrease in this case) to reduce the time period difference.

Convert the difference in length to millimeters (mm) for precision.

By performing these calculations, you can determine the specific amount by which you should decrease the pendulum length in millimeters.

Answer:

Alternating

Explanation:

Answer:

To calculate the depth at section B, 500 m downstream of section A, we can use the Chezy formula:

V = C*R^(1/2)

Where V is the velocity, C is the Chezy coefficient, and R is the hydraulic radius.

a) Using only one step:

Since the flow is non-uniform, the velocity at section B can be assumed to be the same as at section A. Therefore, the depth at section B can be calculated using the same Chezy coefficient and hydraulic radius as at section A.

Hydraulic Radius (R) = A/P = (width * depth) / 2

R_A = (4 * 2.6) / 2 = 5.2 m

R_B = R_A = 5.2 m

Chezy coefficient (C) = (V^2 * n) / (2 * g * R^(1/2))

C = (15^2 * 0.016) / (2 * 9.81 * 5.2^(1/2)) = 1.94

Now we can use the Chezy formula to calculate the depth at section B

V = C*R^(1/2)

V = 1.94 * 5.2^(1/2) = 3.23 m/s

b) Using two steps:

First, we can calculate the velocity at section B using the continuity equation:

Q = A1 * V1 = A2 * V2

15 = (4 * 2.6 * 3.23) = (4 * y * V2)

V2 = (15 / 4) / y = 3.75/y m/s

Next, we can use the Chezy formula and the velocity at section B to calculate the depth at section B:

V = C*R^(1/2)

y = V^2 * n / (C^2 * g)

y = (3.75/y)^2 * 0.016 / (1.94^2 * 9.81)

y = 2.34 m

So, the depth at section B is 2.34 m by using two steps.

Note: The above calculations are based on the assumption that the slope is uniform along the channel and the flow is steady. In practice, other factors such as channel roughness and boundary conditions may also have an impact on the depth of flow.
