Flow is considered to be real and compressible; the discharge process was analyzed at relatively high …
In a nozzle or other constriction, the discharge coefficient (also known as coefficient of discharge or efflux coefficient) is the ratio of the actual discharge to the ideal discharge, i.e., the ratio of the mass flow rate at the discharge end of the nozzle to that of an ideal nozzle which expands an identical working fluid from the same initial conditions to the same exit pressures. Mathematically the discharge coefficient may be related to the mass flow rate of a fluid through … WebThe study determined that the discharge coefficient increased with decreasing head values. The study also found that the discharge coefficient decreased as the height above the floor was increased, up to a certain point. Another factor found to affect the discharge coefficient was the orifice diameter to riser diameter, or dD ratio. The
