The co-efficient of discharge of an orificemeter is a function of ________________?
Correct answer: C. Both A. and B.
- A. Reynolds number at the orifice
- B. Ratio of orifice dia to pipe dia
- C. Both A. and B.
- D. None of the above parameters, and has a constant value of 0.61
Explanation
The discharge coefficient depends mainly on the Reynolds number and the diameter ratio, β = d_orifice/d_pipe. Hence both listed parameters affect the relationship between actual and ideal flow.
