1. How you will select a heat exchanger for different type of fluids.

Question

Accepted Answer

The selection of a heat exchanger for different fluids depends on factors such as fluid properties, flow rates, and heat transfer requirements.

Identify the properties of the fluids such as viscosity, density, and thermal conductivity.
Determine the flow rates and pressure drops of the fluids.
Select the appropriate type of heat exchanger such as shell and tube, plate and frame, or spiral.
Consider the heat transfer requirements and design parameters such as surface area and overall heat transfer coefficient.
Example: For high viscosity fluids, a shell and tube heat exchanger may be more suitable due to its larger flow area and lower pressure drop.
Example: For fluids with high fouling potential, a plate and frame heat exchanger may be preferred for easier cleaning and maintenance.
