Water Hammer Pressure Increase

Water Hammer Pressure Increase Formula

\( p_{inc} =   \frac { 0.070 v l  }   { t  } + p_i  \)          \( pressure \; increase  \;=\;   \frac { 0.070  \;\;x\;\;  flow \; velocity  \;\;x\;\;  upstream \; pipe \; length  }  { valve \; closing \; time  } \;+\;  inlet \; pressure \)        

Where:

\( p_{inc} \) = pressure increase

\( l \) = upstream pipe length

\( p_i\) = inlet pressure

\( t \) = valve closing time

\( v \) = flow velocity
