Water Flow Rate Through an Orifice

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Water Flow Rate Through an Orifice formula

\(Q_w = 0.0865 \cdot C_d  \cdot  \left(  \frac  {d_o} {4.654 } \right)^2  \cdot \sqrt { \frac { p_1 - p_2 } { SG }  }   \)

Where:

\(Q_w\) = water flow rate

\(d_o\) = diameter of orifice

\(C_d\) = discharge coefficient

\(p_1\) = primary pressure

\(p_2\) = secondary pressure

\(SG\) = water specific gravity
