discharge coefficient

[′dis‚chärj ‚kō·i′fish·ənt] (fluid mechanics) In a nozzle or other constriction, 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 pressure. Also known as coefficient of discharge.

coefficient of discharge

1.The ratio of the actual discharge of water through an opening to its corresponding theoretical value. 2. The ratio of effective area to the free area of an air diffuser.
