Water Hammer Maximum Surge Pressure for Water
Water Hammer Maximum Surge Pressure for Water Formula
| \(\large{ p_{spw} = \frac { \alpha\; \Delta v_w } { 2.31\;g } }\) |
Where:
| Units | 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 | \(\large{\frac{ft}{sec}}\) | \(\large{\frac{m}{s}}\) |
Solve for:
| \(\large{ g = \frac { \alpha \; \Delta v_w } { 2.31\; p_{spw} } }\) | |
| \(\large{ \alpha = \frac { 2.31 \; p_{spw} \;g } { \Delta v_w } }\) | |
| \(\large{ \Delta v_w = \frac { 2.31 \; p_{spw} \;g } { \alpha } }\) |
