| \(\large{ g }\) = gravitational acceleration | \(\large{\frac{ft}{sec^2}}\) | \(\large{\frac{m}{s^2}}\) |
| \(\large{ \Delta v }\) = fluid velocity change | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
| \(\large{ p_{sf} }\) = maximum surge pressure for fluid | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ p_{sw} }\) = maximum surge pressure for water | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ h_{sf} }\) = maximum surge pressure head in length of fluid | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ \alpha }\) (Greek symbol alpha) = pressure wave velocity | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
| \(\large{ \gamma_f } \) (Greek symbol gamma) = unit weight of fluid | \(\large{\frac{lbm}{ft^3}}\) | \(\large{\frac{N}{m^3}}\) |
