Water Hammer Maximum Surge Pressure for a Fluid

Written by Jerry Ratzlaff. Posted in Fluid Mechanics

formula

\(P_{fluid} = \frac { a \Delta v y } { 144 g }   \)

Where:

\(P\) = maximum surge pressure

\(H\) = hammer (surge fluid)

\(a\) = pressure wave velocity (acceleration)

\( \Delta v\) = velocity differential

\(g\) = gravitational acceleration

\(y\) = unit weight of fluid

Solve for:

\(a = \frac { 144 P g } { \Delta v y }   \)

\(\Delta v = \frac { 144 P g } { a y }   \)

\(g = \frac { a \Delta v y } { 144 P_{fluid} }   \)

\(y = \frac { 144 P_{fluid} g } { a \Delta v }   \)
