## Hydraulic Power formula

$$\large{ P_h = \dot m_f \; g \; h }$$

$$\large{ P_h = \rho_w \; Q \; g \; h }$$

Symbol 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 $$\large{\frac{ft^3}{sec}}$$ $$\large{\frac{m^3}{s}}$$
