What is heat duty? And design the heat exchanger by Kern's method.

Question

Accepted Answer

Heat duty is the amount of heat energy required to be transferred in a heat exchanger.

Heat duty is calculated based on the temperature difference between the hot and cold fluids, and the flow rates of the fluids.
Kern's method is a widely used method for designing heat exchangers.
It involves calculating the overall heat transfer coefficient and the heat transfer area required for the given heat duty.
The design process also involves selecting the appropriate type of heat exchanger based on the specific application.
Examples of heat exchangers include shell and tube, plate and frame, and spiral heat exchangers.
