Steam Pressure Loss through Piping formula

\(\large{ p_l =   \frac{ \mu \; l  \; v_s{^2}  }{  24 \; d \; g  \; \upsilon }   }\)   

Where:

 Units English Metric
\(\large{ p_l }\) = steam pressure loss \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ \mu }\)  (Greek symbol mu) = friction coefficient of steam \(\large{dimensionless}\)
\(\large{ g }\)  = gravitational acceleration \(\large{\frac{ft}{sec^2}}\) \(\large{\frac{m}{s^2}}\)
\(\large{ l }\) = length of pipe \(\large{ ft }\) \(\large{ m }\)
\(\large{ d }\) = pipe inside diameter \(\large{in}\) \(\large{mm}\)
\(\large{ \upsilon }\)  (Greek symbol upsilon) = specific volume of steam \(\large{\frac{ft^3}{lbm}}\) \(\large{\frac{m^3}{kg}}\)
\(\large{ v_s }\) = steam velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
