Water Hammer Maximum Surge Pressure for Water Formula

\(\large{  p_{spw}  =  \frac { \alpha\;  \Delta\; v_w   }   { 2.31\;g  }  }\)                         

Where:

\(\large{ p_{spw} }\) = maximum surge pressure for water

\(\large{ g }\) = gravitational acceleration

\(\large{ \alpha }\)  (Greek symbol alpha) = pressure wave velocity

\(\large{ \Delta v_w }\) = water velocity change

Solve for:

\(\large{  g  =  \frac { \alpha \; \Delta\; v_w   }   { 2.31\; p_{spw}  }  }\)

\(\large{  \alpha  =  \frac { 2.31 \; p_{spw} \;g  }   { \Delta\; v_w  }   }\)

\(\large{  \Delta v_w  =  \frac { 2.31 \; p_{spw} \;g  }   { \alpha  }   }\)
