Steam Velocity through Piping

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Steam Velocity through Piping formula

\(\large{ v_s =  \frac{ Q_s \;  \upsilon }{ 3600 \; \pi \; { \left( \frac {d}{24} \right) ^2  }   }  }\)   

Where:

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