It is useful in estimating runoff The discharge coefficient is proportional to the inverse of the square root of delta P, so if your pressure losses go down because of increasing Reynolds number, your discharge coefficient goes up (assuming constant mass flow rate). From a physical standpoint, I'd point at how the velocity profile in a pipe changes as you increase Reynolds number.

Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity. 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 theoretical 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.
