formula

\(Q = C_v A \sqrt {2 \cdot g \cdot \Delta h} = C_v A \sqrt {  \frac { 2 \Delta P} {\rho}  }  \)

Where:

\(Q\) = volumetric flow rate / flow rate

\(C_v\) = flow coefficient

\(A\) = cross section area

\(\Delta P\) = pressure loss

\(\rho\) (Greek symbol rho) = density

\(g\) = gravitational acceleration

\(\Delta h\) = head loss
