Which hydraulic turbine is most suitable for a site with very high head and relatively low discharge?
Correct answer: A. Pelton turbine
- A. Pelton turbine
- B. Kaplan turbine
- C. Propeller turbine
- D. Cross-flow turbine
Explanation
A Pelton turbine is an impulse turbine designed for high-head, low-discharge conditions. Kaplan and propeller turbines are generally selected for low heads and large discharges, while cross-flow turbines suit smaller installations over a broader range.

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.
