Formulas that use Water Pressure Loss Through Piping

\(\large{ p_l = \frac{ \mu \;  l  \; {v_w}^2 \; \rho  \; SG    }{ 24 \;d \; g }  }\)   
\(\large{ p_l =  4.53 \; l \;  \frac{ \frac{ Q_w }{ C }^{1.852}   }{ d^{4.857} }  }\)   

Where:

\(\large{ p_l }\) = water pressure loss

\(\large{ \rho }\)  (Greek symbol rho) = density of water

\(\large{ \mu }\)  (Greek symbol mu) = friction coefficient of water

\(\large{ g }\) = gravitational acceleration

\(\large{ l }\) = length of pipe

\(\large{ C }\) = pipe coefficient

\(\large{ d }\) = pipe inside diameter

\(\large{ SG }\) = specific gravity of water

\(\large{ Q_w }\) = water flow rate

\(\large{ v_w }\) = water velocity
