Water Hammer Upstream Pipe Length
| Water Hammer Upstream Pipe Length Formula | ||
| \( WH_{upl} \;=\; \dfrac{ a \cdot v }{ g }\) (Water Hammer Upstream Pipe Length) \( a \;=\; \dfrac{ WH_{upl} \cdot g }{ v }\) \( v \;=\; \dfrac{ WH_{upl} \cdot g }{ a }\) \( g \;=\; \dfrac{ a \cdot v }{ WH_{upl} }\) | ||
| Symbol | English | Metric | 
| \( WH_{upl} \) = water hammer upstream pipe length | \(ft\) | - | 
| \( a \) = speed of sound of fluid | \(ft\;/\;sec\) | - | 
| \( v \) = velocity of fluid | \(ft\;/\;sec\) | - | 
| \( g \) = gravitational acceleration | \(ft\;/\;sec^2\) | - |
