In a reciprocating pump, the air vessel is primarily used to:
Correct answer: A. Reduce fluctuation in discharge and power requirement
- A. Reduce fluctuation in discharge and power requirement
- B. Increase the water's density
- C. Convert pressure energy into turbine shaft power
- D. Prevent all pipe friction losses
Explanation
An air vessel stores and releases water during the pumping cycle, making discharge more uniform and reducing acceleration effects and power fluctuations. It does not remove pipe friction or perform the energy conversion of 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.
