The coefficient of discharge for an orifice meter is in the range
- A. 0.97 to 0.99
- B. 0.93 to 0.98
- C. 0.62 to 0.65
- D. 0.51 to 0.55
Answer: C. 0.62 to 0.65
Explanation: The coefficient of discharge for an orifice meter is typically in the range of 0.62 to 0.65, which depends on the Reynolds number and the area ratio. By comparison, a venturimeter has a significantly higher coefficient of discharge, usually falling between 0.95 and 0.99.
