Q2. Why the motor capacity is in Kw and for transformer it is in kva?
Ans. 
Motor capacity is in Kw because it measures active power while transformer capacity is in kVA because it measures apparent power.
• Motor capacity is measured in Kw because it represents the active power that the motor can produce.

• Transformers are rated in kVA because they are designed to handle both active and reactive power.

• kVA is a measure of apparent power, which is the combination of active power and reactive power.

Q2. How to find heat duty?
Ans. 
Heat duty can be found by calculating the amount of heat required to raise the temperature of a substance or system.
• Determine the mass of the substance or system

• Determine the specific heat capacity of the substance

• Determine the change in temperature

• Use the formula Q = mcΔT to calculate the heat duty

• Q = heat duty, m = mass, c = specific heat capacity, ΔT = change in temperature
