What happens to the coefficient of velocity (Cv) in a perfectly ideal fluid flow?

7. What happens to the coefficient of velocity (Cv) in a perfectly ideal fluid flow?

  1. Cv is zero
  2. Cv is one
  3. Cv is less than zero
  4. Cv is greater than one

Answer: B) Cv is one.

Explanation:

In a perfectly ideal fluid flow, where there are no energy losses, the actual velocity equals the theoretical velocity, resulting in a coefficient of velocity (Cv) of 1.8.
