Question

The value of coefficient of discharge (Cd) for a venturimeter usually lies between

• A. 0.55 to 0.58
• B. 0.66 to 0.68
• C. 0.77 to 0.88
• D. 0.95 to 0.98

Answer 1

Answer:

D. 0.95 to 0.98

Coefficient of discharge is the ratio of actual discharge to the theoretical discharge. For venturimeter, the value of Cd lies between 0.95 to 0.98. Similarly, for orifice meter, it is 0.62 to 0.65 and for nozzle meter, it is 0.93 to 0.98.
