What is the main function of a hydraulic pump in a water supply system?
Correct answer: C. To convert shaft work into hydraulic energy
- A. To convert hydraulic energy into shaft work
- B. To convert heat energy into pressure energy
- C. To convert shaft work into hydraulic energy
- D. To convert pressure energy into electrical energy
Explanation
A pump receives mechanical or shaft power and transfers energy to the liquid, increasing its pressure head, velocity head or elevation head. The reverse conversion, from hydraulic energy to shaft work, is performed by a turbine.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
