Water Velocity through Piping
Water Velocity Through Piping formulas
| \(\large{ v_w = \frac{ 0.134 \; Q_w }{ 3600 \; \pi \; { \left( \frac {d}{24} \right) ^2 } } }\) | |
| \(\large{ v_w = 0.408 \; \frac{ Q_w }{ d^2 } }\) |
Where:
| Units | English | Metric |
| \(\large{ v_w }\) = water velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
| \(\large{ \pi }\) = Pi | \(\large{3.141 592 653 ...}\) | |
| \(\large{ d }\) = pipe inside diameter | \(\large{in}\) | \(\large{mm}\) |
| \(\large{ Q_w }\) = water flow rate | \(\large{\frac{ft^3}{sec}}\) | \(\large{\frac{m^3}{s}}\) |
