Water Velocity through Piping

on 05 April 2016. 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	\(3.141 592 653 ...\)	\(3.141 592 653 ...\)
\( d \) = 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	\(in\)	\(mm\)
