The theoretical power available from water passing through a hydraulic turbine is proportional to:
Correct answer: A. ρgQH
- A. ρgQH
- B. ρQ/(gH)
- C. gH/(ρQ)
- D. ρgH/Q
Explanation
The water power supplied to a turbine is ρgQH, where ρ is density, g is gravitational acceleration, Q is discharge, and H is head. The actual turbine output is this theoretical power multiplied by the appropriate efficiency.

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.
