Water Pipe Sizing formula

\(\large{ d =   \frac{1}{12}   \sqrt {   \frac { 0.134 \; Q_w } { 3600 }   \;  \frac { 4 } { \pi }   }  }\)   

Where:

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