Hydraulic Power formula

\(\large{ P_h = \dot m_f \; g \; h }\)   
\(\large{ P_h = \rho_w \; Q \; g \; h }\)  

Where:

 Units English Metric
\(\large{ P_h }\) = hydraulic power  \(\large{\frac{lbm-ft^2}{sec}}\)  \(\large{\frac{kg-m^2}{s}}\) 
\(\large{ g }\) = gravitational acceleration \(\large{\frac{ft}{sec^2}}\) \(\large{\frac{m}{s^2}}\)
\(\large{ h }\) = hydraulic head \(\large{in}\) \(\large{m}\)
\(\large{ \rho_w }\)   (Greek symbol rho) = water density by temperature \(\large{\frac{lbm}{ft^3}}\) \(\large{\frac{kg}{m^3}}\)
\(\large{ \dot m_f }\) = water mass flow rate \(\large{\frac{lbm}{sec}}\) \(\large{\frac{kg}{s}}\)
\(\large{ Q }\) = water volumetric flow rate \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
