The rate of heat removal from refrigerator  is 0.703 kw.

A Carnot refrigerator removes the heat from the cold reservoir and discharges it to the hot reservoir with the help of external work input.

The Carnot coefficient of performance (COP) of a refrigerator is given as:

COP = QL / W

where,

QL is the heat removed from the cold reservoir

W is the work input in the refrigerator.

Since the refrigerator is Carnot, the coefficient of performance is COP = TC / (TH - TC)

The temperature of the cold reservoir is Tc = 5.1°C

The temperature of the hot reservoir is Th = 15.9°C.

The coefficient of performance of the refrigerator is: COP = 5.1 / (15.9 - 5.1)= 0.406

The work input required by the refrigerator is W = QL / COP

where, QL is the heat removed from the cold reservoir.

The heat removed from the cold reservoir is equal to the heat discharged to the hot reservoir since the refrigerator is Carnot.

The rate of heat removal from the refrigerator is given as: P = QL = W * COP = 1731 * 0.406= 702.786 W= 0.7028 kW

Thus, the rate of heat removal from the refrigerator is 0.7028 kW.

Answer: 0.703 kW (rounded to 3 decimal places)

To find the theoretical yield of a thermal decomposition, you need to balance the equation of the thermal decomposition reaction and use stoichiometry to determine the amount of product that should be produced.

The theoretical yield is the maximum amount of product that can be obtained from a given amount of reactant. In thermal decomposition reactions, a single compound is broken down into two or more products by heating it to a high temperature.In order to find the theoretical yield of a thermal decomposition reaction, you first need to balance the equation for the reaction.  You can calculate the amount of product that should be produced based on the amount of limiting reactant that was used.Finally, you can calculate the theoretical yield of the reaction by multiplying the amount of product that should be produced by the percent yield. The percent yield is the actual yield divided by the theoretical yield, multiplied by 100%.

To find the theoretical yield of a thermal decomposition reaction, follow these steps:1. Write the balanced equation for the reaction. For example, the thermal decomposition of calcium carbonate can be written as:CaCO3(s) → CaO(s) + CO2(g)2. Determine the molar mass of the reactant and the product. For example, the molar mass of calcium carbonate is 100.09 g/mol. The molar mass of calcium oxide is 56.08 g/mol and the molar mass of carbon dioxide is 44.01 g/mol.3.  For example, if 0.050 mol of calcium carbonate is used, 0.050 mol of calcium oxide should be produced.7. Convert the moles of product to grams. For example, the mass of calcium oxide that should be produced is:0.050 mol × 56.08 g/mol = 2.80 g8. Calculate the percent yield of the reaction. The percent yield is the actual yield divided by the theoretical yield, multiplied by 100%. For example, if the actual yield of calcium oxide was 2.50 g, the percent yield would be:2.50 g / 2.80 g × 100% = 89.3%9. Calculate the theoretical yield of the reaction. The theoretical yield is the maximum amount of product that can be obtained from a given amount of reactant. For example, the theoretical yield of calcium oxide would be:0.050 mol × 56.08 g/mol = 2.80 gTherefore, the main answer to the question "how to find the theoretical yield of a thermal decomposition" is that to find the theoretical yield of a thermal decomposition, you need to balance the equation of the thermal decomposition reaction and use stoichiometry to determine the amount of product that should be produced.

To calculate the resistive power loss, we need to determine the total resistance of the cable and then use the formula \(\text{P}=\text{I}^{2}\text{R}\), where P is the power loss, I is the rms current, and R is the total resistance.

Given that the resistance of the cable is 0.50Ω/km, the total resistance for 200 km can be calculated as follows:

Total Resistance = (Resistance per kilometer) × (Total distance)

\(\text{R}=0.50\times200\\\text{R}=100\Omega\)

Resistive power refers to the power loss or dissipation that occurs in a circuit or system due to the resistance of its components.

The Hall-Taylor criterion for flooding can be given by the expression, y = 0.074 [ (ρL /ρV) (σ /ρL gD) ]0.25

where, y is the maximum permissible liquid flow rate per unit cross-sectional area,

ρL is the density of the liquid,

ρV is the density of the vapour,

σ is the surface tension of the liquid,

D is the diameter of the tube,

and g is the gravitational acceleration.

The given details are,

Vapour flow rate, Q = 8,000 kg/h

Liquid flow rate, L = 7,000 kg/h

Pressure, P = 1 bar

Inner diameter of the tube, d = 50 mm

Boiling point of benzene, ρL = 840 kg/m³

Density of the vapour phase benzene, ρV = 2.7 kg/m³

Surface tension of benzene, σ = 0.0285 N/m

The gravitational acceleration, g = 9.81 m/s²

Diameter of the tube, D = 50 mm = 0.05 m

As the given parameters are in kg/h, we need to convert them into kg/s.

To convert kg/h to kg/s, we need to divide the given values by 3600 kg/h = 8,000 / 3600 = 2.22 kg/s

Liquid flow rate, L = 7,000 / 3600 = 1.94 kg/s

From the given details,ρL = 840 kg/m³ρV = 2.7 kg/m³σ = 0.0285 N/mg = 9.81 m/s²D = 0.05 m

Substituting these values in the above equation, the Hall-Taylor criterion for flooding can be given by,

y = 0.074 [ (840 / 2.7) (0.0285 / 840 × 9.81 × 0.05) ]0.25y = 0.0049 m³/s/m²

Now, the liquid flow rate per unit cross-sectional area is given by,L / A = y

where, A is the cross-sectional area of the tube.

As the tube is of 50 mm diameter, the cross-sectional area can be given by,

A = πD² / 4A = π (0.05)² / 4A = 1.963 × 10⁻⁴ m²

The maximum permissible liquid flow rate per unit cross-sectional area is given by,L / A = 0.0049L = 0.0049 × A

Thus, L = 0.0049 × 1.963 × 10⁻⁴L = 9.61 × 10⁻⁷ m³/s

The given liquid flow rate is, L = 1.94 kg/s = 0.00194 m³/s

The maximum permissible liquid flow rate per unit cross-sectional area, L / A = 9.61 × 10⁻⁷ m³/s

Thus, the tubes are not likely to flood as the maximum permissible liquid flow rate per unit cross-sectional area is more than the actual liquid flow rate per unit cross-sectional area.

Flooding should be controlled in condensers for the following reasons:

To prevent the condensers from becoming filled with liquid and to prevent the interference of liquid with the condensation process.

To prevent the flooding of liquid in the tubes that can result in inefficient operation, decreased output, and increased maintenance cost.

To prevent the liquid in the tubes from being entrained into the vapour and causing the contamination of downstream equipment.

To prevent the formation of a continuous film of liquid in the tubes that can result in the reduction of the heat transfer coefficient and increased resistance to vapour flow.

To avoid hydraulic problems that can cause the development of high pressure drops and uneven flow distribution, which can result in tube erosion, leakage, and other problems.

Explanation:

Work = Force X Distance

We need to know the value of θ to calculate Fnet and determine if the force can move the crate. The sum of forces opposed to the desired movement would be equal to the force of friction, which is 0.24 * 20kg * 9.8m/s^2 * cos(θ).

To determine if the force of 200N can move the crate, we need to calculate the force of friction acting on the crate. Since the crate is at rest initially, we need to use the static coefficient of friction (μs). The formula for calculating the force of friction is Ffriction = μs * Fn, where Fn is the normal force acting on the crate.
To find Fn, we need to resolve the weight of the crate into its components parallel and perpendicular to the inclined surface. The perpendicular component cancels out with the normal force acting on the crate, leaving only the parallel component. The parallel component of the weight is Wsinθ, where θ is the angle of the inclined surface.
Using this, we can calculate the force of friction:
Ffriction = μs * Fn
Fn = mgcosθ
Ffriction = μs * mgcosθ
Ffriction = 0.24 * 20kg * 9.8m/s^2 * cos(θ)
Now we can calculate the net force acting on the crate:
Fnet = F - Ffriction
Fnet = 200N - 0.24 * 20kg * 9.8m/s^2 * cos(θ)
If Fnet is positive, then the force is enough to move the crate. If Fnet is negative, then the force is not enough to move the crate.
Therefore, we need to know the value of θ to calculate Fnet and determine if the force can move the crate. The sum of forces opposed to the desired movement would be equal to the force of friction, which is 0.24 * 20kg * 9.8m/s^2 * cos(θ).
In conclusion, the answer cannot be provided without knowing the value of θ.

Convection plays a crucial role in producing the rain shadow effect because it is the mechanism that causes the air to rise and cool on the windward side of the mountain range.

What is Convection?

The rain shadow effect is a phenomenon that occurs when moist air from an ocean or other body of water encounters a mountain range, causing the air to rise and cool, leading to precipitation on the windward side of the mountain range. However, as the air descends down the leeward side of the mountain range, it warms and dries out, creating a rain shadow region with much less precipitation.

Convection plays a crucial role in producing the rain shadow effect because it is the mechanism that causes the air to rise and cool on the windward side of the mountain range. When the moist air encounters the mountain range, it is forced to rise due to the topography, leading to the formation of clouds and precipitation. This rising air is driven by convective processes, which occur as a result of temperature differences within the atmosphere.

The magnetic field between the plates is: sinusoidal and its amplitude is proportional to the frequency of the source.

When a sinusoidal emf is connected to a parallel plate capacitor, an alternating electric field is produced between the plates. This electric field causes a displacement current which in turn produces a magnetic field between the plates.

The amplitude of this magnetic field is proportional to the frequency of the source. Therefore, as the frequency of the source increases, the amplitude of the magnetic field between the plates also increases.
