It is defined as the ratio of the area of the jet at the vena contracta to the area of the orifice. The theoretical value of the coefficient of contraction for a sharp-edged orifice is 0.611. This means that the area of the jet at the vena contracta is 0.611 times the area of the orifice.<\/p>\n<p>The coefficient of contraction is affected by a number of factors, including the shape of the orifice, the Reynolds number, and the surface roughness of the orifice. The theoretical value of the coefficient of contraction is only valid for a sharp-edged orifice in an inviscid fluid.
