Water Velocity through Piping

on . Posted in Fluid Dynamics

     

Water Velocity Through Piping formula

\( v_w =  0.134 \; Q_w \;/\; 3600 \; \pi \; { \left( d\;/\;24 \right) ^2  }  \) 
Symbol English Metric
\( v_w \) = water velocity \(ft\;/\;sec\) \(m\;/\;s\)
\( Q_w \) = water flow rate \(ft^3\;/\;sec\) \(m^3\;/\;s\)
\( \pi \) = Pi \(3.141 592 653 ...\)
\( d \) = pipe inside diameter \(in\) \(mm\)

    

Water Velocity Through Piping formula

\( v_w =  0.408 \; ( Q_w \;/\; d^2 )   \)
Symbol English Metric
\( v_w \) = water velocity \(ft\;/\;sec\) \(m\;/\;s\)
\( Q_w \) = water flow rate \(ft^3\;/\;sec\) \(m^3\;/\;s\)
\( d \) = pipe inside diameter \(in\) \(mm\)
