Water Flow Rate through Piping

Water Flow Rate through Piping formula

\(\large{ Q_w = \left( \frac{ 3600 }{ 0.134 } \; \pi \right)  \left(  v_w { \left( \frac{d}{24} \right) ^2  }  \right)  }\)   

Where:

 Units English Metric
\(\large{ Q_w }\) = water flow rate through piping \(\large{\frac{ft^3}{sec}}\) \(\large{\frac{m^3}{s}}\)
\(\large{ \pi }\) = Pi \(\large{3.141 592 653 ...}\)
\(\large{ d }\) = pipe inside diameter \(\large{ in }\) \(\large{ mm }\)
\(\large{ v_w }\) = water velocity through piping \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
