Water Hammer Upstream Pipe Length
Water Hammer Upstream Pipe Length Formula |
||
| \(\large{ l = \frac { \left( \; p_{inc} \;-\; p_i \; \right)\; t } { 0.070 \;v } }\) | ||
| Symbol | English | Metric |
| \(\large{ l }\) = upstream pipe length | \(\large{ft}\) | \(\large{m}\) |
| \(\large{ v }\) = flow velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
| \(\large{ p_i }\) = inlet pressure | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_{inc} }\) = pressure increase | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ t }\) = valve closing time | \(\large{sec}\) | \(\large{s}\) |
