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

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.

• T...read more
