The ratio of actual discharge to theoretical discharge through an orifice is equal to______________?
Correct answer: A. Cc . Cv
- A. Cc . Cv
- B. Cc . Cd
- C. Cv . Cd
- D. Cd/Cv
Explanation
The discharge coefficient is defined as actual discharge divided by theoretical discharge, so the ratio is Cd. Since Cd equals the product of the contraction and velocity coefficients, the equivalent expression is Cc × Cv.
