Cd for the orifice plate varies from ___________________?
Correct answer: A. 0.58 to 0.8
- A. 0.58 to 0.8
- B. 0.93 to 0.98
- C. 0.2 to 0.3
- D. 0.02 to 0.03
Explanation
The discharge coefficient of a standard sharp-edged orifice plate is typically around 0.6, with a practical range close to 0.58 to 0.8 depending on geometry and Reynolds number. The higher range given for nozzles is not the usual orifice-plate range.
