What is the principal energy conversion performed by a hydraulic turbine?
Correct answer: D. Hydraulic energy into mechanical energy
- A. Electrical energy into potential energy
- B. Mechanical energy into hydraulic energy
- C. Thermal energy into pressure energy
- D. Hydraulic energy into mechanical energy
Explanation
A turbine extracts energy from flowing or falling water and delivers it as shaft mechanical power. A pump performs the opposite principal conversion by adding mechanical energy to water.

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.
