Cd, Cc and Cv are related (for flow through an orifice) as (where, Cd = discharge co-efficient, Cc = co-efficient of contraction = (area of jet at vena-contracta/area of opening), Cv = co-efficient of velocity = (actual velocity at vena-contracta/theoretical velocity)?
Correct answer: B. Cd = Cc.Cv
- A. Cd = Cc/Cv
- B. Cd = Cc.Cv
- C. Cd = Cv/ Cc
- D. None of these
Explanation
The discharge coefficient combines contraction and velocity effects, so C_d = C_cC_v. The contraction coefficient accounts for reduced jet area, while the velocity coefficient accounts for actual versus theoretical velocity.
