Water Hammer Maximum Surge Pressure for Water Formula

\(\large{  p_{spw}  =  \frac{ \alpha\; \Delta v_w }{ 2.31\;g }  }\) 
Symbol English Metric
\(\large{ p_{spw} }\) = maximum surge pressure for water \(\large{\frac{lbf}{in^2}}\)  \(\large{Pa}\) 
\(\large{ g }\) = gravitational acceleration \(\large{\frac{ft}{sec^2}}\) \(\large{\frac{m}{s^2}}\)
\(\large{ \alpha }\)  (Greek symbol alpha) = pressure wave velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ \Delta v_w }\) = water velocity change \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
