Q1. What are the energy conversion take place in centrifugal pumps?
Ans. 
Energy conversion in centrifugal pumps involves mechanical energy being converted to kinetic energy and then to potential energy.
• Mechanical energy from the motor is converted to kinetic energy in the rotating impeller

• Kinetic energy is then converted to potential energy in the volute casing

• The potential energy is then used to increase the pressure and flow of the fluid being pumped

• Efficiency of the pump is crucial in mi
