Discharge Coefficient
Discharge coefficient, abbreviated as \(C_d\), also called coefficient of discharge, a dimensionless number, is the ratio of actual discharge to the theoretical discharge.

\(\large{ C_d }\) = discharge coefficient | \(\large{ dimensionless }\) | |
\(\large{ \rho }\) (Greek symbol rho) = density of fluid | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{kg}{m^3}}\) |
\(\large{ \dot m_f }\) = mass flow rate | \(\large{\frac{lbm}{sec}}\) | \(\large{\frac{kg}{s}}\) |
\(\large{ Q }\) = volumetric flow rate | \(\large{\frac{ft^3}{sec}}\) | \(\large{\frac{m^3}{s}}\) |
