The discharge co-efficient for an orifice meter does not depend upon the ___________________?
Correct answer: A. Pipe length
- A. Pipe length
- B. Ratio of pipe diameter to orifice diameter
- C. Type of orifice & the Reynolds number
- D. Pipe diameter
Explanation
An orifice-meter discharge coefficient depends mainly on the diameter ratio, orifice design and Reynolds number. Straight pipe length does not directly enter the coefficient, although adequate upstream and downstream lengths are needed for proper installation.
