Q1. Explain Heat duty of heat echanger
Ans. 
Heat duty of a heat exchanger refers to the amount of heat transferred between the hot and cold fluids.
• Heat duty is the heat transfer rate or the amount of heat energy transferred per unit time.

• It is calculated by multiplying the mass flow rate of the fluid by the specific heat capacity and the temperature difference between the hot and cold fluids.

• The heat duty determines the size and design of the heat exchanger.
