Question

The ratio of actual discharge of a jet of water to its theoretical discharge is known as-
1. Coefficient of velocity 
2. Coefficient of discharge
3. Coefficient of viscosity 
4. Coefficient of contraction

Answer 1

Correct Answer - Option 2 : Coefficient of discharge

Explanation:

Coefficient of discharge is the ratio of actual discharge to the theoretical discharge.

Coefficient of discharge

⇒ Venturimeter – 0.95 to 0.98

⇒ Orifice meter – 0.62 to 0.65

⇒ Nozzle meter – 0.93 to 0.98

The coefficient of discharge for the venturimeter lies is higher than the nozzle meter and orifice meter.
