Water Flow Rate through Piping formula |
||
| \( Q_w \;=\; \left( \dfrac{ 3600 }{ 0.134 } \cdot \pi \right) \cdot \left( v_w \cdot \left( \dfrac{ d}{24} \right)^2 \right) \) | ||
| Symbol | English | Metric |
| \( Q_w \) = Water Flow Rate Through Piping | \(ft^3\;/\;sec\) | \(m^3\;/\;s\) |
| \( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
| \( v_w \) = Water Velocity Through Piping | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( d \) = Pipe Inside Diameter | \( in \) | \( mm \) |
