Q2. Design of heat exchanger
Ans. 
Heat exchangers are devices used to transfer heat between two or more fluids.
• Heat exchangers can be classified based on their construction (e.g. shell and tube, plate, finned tube)

• Design considerations include fluid flow rates, temperature ranges, material selection, and pressure drop

• Efficiency of heat exchangers can be improved by increasing surface area for heat transfer

• Examples of heat exchangers include car radiato...read more

Q1. What is the difference between centrifugal pump and reciprocating pump
Ans. 
Centrifugal pumps use impellers to move fluid while reciprocating pumps use pistons or diaphragms.
• Centrifugal pumps are more commonly used for high flow rate and low viscosity fluids while reciprocating pumps are used for low flow rate and high viscosity fluids.

• Centrifugal pumps are generally less expensive and require less maintenance than reciprocating pumps.

• Reciprocating pumps are better suited for applications wher...read more
