What Is Coefficient Of Contraction? |
|
Answer» Coefficient of contraction is the ratio of AREA of jet at VENA contracta to the area of orifice. The typical value MAY be taken as 0.64 for a sharp orifice (concentric with the FLOW channel). The smaller the value, the more effect the vena contracta has. Coefficient of contraction is the ratio of area of jet at vena contracta to the area of orifice.
