Coefficient of Contraction Formula

Coefficient of Contraction = Coefficient of Discharge/Coefficient of Velocity
Cc = Cd/Cv

What is Coefficient of Contraction?

The coefficient of contraction is defined as the ratio between the area of the jet at the vena contracta and the area of the orifice.The typical value may be taken as 0.611 for a sharp orifice (concentric with the flow channel). The smaller the value, the more effect the vena contracta has.
