Add your answer
Q2. What are the Types of pumps
Ans. 
Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps: move fluid parallel to the impeller shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, A
