Gas Pressure Loss through Piping Formula
\( p_l \;=\; \dfrac{ \mu \cdot l \cdot v_g^2 \cdot \rho }{ 2 \cdot d }\) (Gas Pressure Loss through Piping) \( \mu \;=\; \dfrac{ 2 \cdot d \cdot p_l }{ l \cdot v_g^2 \cdot \rho }\) \( l \;=\; \dfrac{ 2 \cdot d \cdot p_l }{ \mu \cdot v_g^2 \cdot \rho }\) \( v_g \;=\; \sqrt{ \dfrac{ 2 \cdot d \cdot p_l }{ \mu \cdot l \cdot \rho } } \) \( \rho \;=\; \dfrac{ 2 \;d \cdot p_l }{ \mu \cdot l \cdot v_g^2 }\) \( d \;=\; \dfrac{ \mu \cdot l \cdot v_g^2 \cdot \rho }{ 2 \cdot p_l }\)
