Gas Pressure Loss through Piping formula
\( p_l = \mu \; l \; v_g^2 \; \rho \;/\; 2 \; d \) (Gas Pressure Loss through Piping) \( \mu = 2 \;d \; p_l \;/\; l \; v_g^2 \; \rho \) \( l = 2 \;d \; p_l \;/\; \mu \; v_g^2 \; \rho \) \( v_g = \sqrt{ 2 \;d \; p_l \;/\; \mu \; l \; \rho } \) \( \rho = 2 \;d \; p_l \;/\; \mu \; l \; v_g^2 \) \( d = \mu \; l \; v_g^2 \; \rho \;/\; 2 \; p_l \)
Symbol	English	Metric
\( p_l \) = gas pressure loss	\(lbf\;/\;in^2\)	\(Pa\)
\( \mu \) (Greek symbol mu) = friction coefficient	\(dimensionless\)
\( l \) = pipe length	\(ft\)	\(m\)
\( v_g \) = velocity of gas	\(ft\;/\;sec\)	\(m\;/\;s\)
\( \rho \) (Greek symbol rho) = density of gas	\(lbm\;/\;ft^3\)	\(kg\;/\;m^3\)
\( d \) = inside diameter of pipe	\(in\)	\(mm\)
