The goal of heat exchanger design is to relate the inlet and outlet temperatures, the overall heat transfer coefficient, and the geometry of the heat exchanger, to the rate of heat transfer between the two fluids

Solution

Goal of heat exchanger design is as follows

Geometry : Determination of required heat transfer area, number of tubes, tube length and diameter, tube layout, number of shell and tube passes, number of baffles

Heat transfer Rate : To estimate the effect of fouling on heat transfer coefficient

Selection of material: To select proper material whose refractoriness has to withstand fluid Temperatures
