Steam Pipe sizing formula

\(\large{ d = 12\;  \sqrt {   \frac { 4 } { \pi }   \;  \frac { Q_s \; \upsilon } {3600 \;v_s}      }  }\) 
Symbol English Metric
\(\large{ d }\) = pipe inside diameter \(\large{in}\) \(\large{mm}\)
\(\large{ \pi }\) = Pi \(\large{3.141 592 653 ...}\)
\(\large{ Q_s }\) = steam flow rate \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ \upsilon }\)  (Greek symbol upsilon) = specific volume of steam \(\large{\frac{ft^3}{lbm}}\) \(\large{\frac{m^3}{kg}}\)
\(\large{ v_s }\) = steam velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
