Discharge Coefficient

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Discharge coefficient (also called coefficient of discharge) is the ratio of actual discharge to the theoretical discharge.

Discharge Coefficient Formula

\(\large{ C_d =   \frac { \dot m_f }  {  \rho Q }   }\)    


\(\large{ C_d }\) = discharge coefficient

\(\large{ \dot m_f }\) = mass flow rate

\(\large{ \rho }\)  (Greek symbol rho) = density of the fluid

\(\large{ Q }\) = volumetric flow rate
