The coefficient of discharge of a hydraulic structure is the ratio of actual discharge to the:
Correct answer: B. Theoretical discharge
- A. Critical discharge
- B. Theoretical discharge
- C. Baseflow discharge
- D. Design flood discharge
Explanation
The coefficient of discharge accounts for departures from ideal flow and is defined as actual discharge divided by theoretical discharge. Design flood discharge is a hydrologic design value, not the reference quantity in this coefficient.

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.
