Surge Pressure Formula
The following formula is used to calculate the Surge Pressure.
Psurge = .8 * D * V
- Where Psurge is the Surge Pressure (psi)
- D is the density (lbs/ft^3)
- V is the velocity (ft/s)
How to Calculate Surge Pressure?
The following two example problems outline how to calculate the Surge Pressure.
Example Problem #1:
- First, determine the density (lbs/ft^3). In this example, the density (lbs/ft^3) is given as 50.
- Next, determine the velocity (ft/s). For this problem, the velocity (ft/s) is given as 125.
- Finally, calculate the Surge Pressure using the equation above:
Psurge = .8 * D * V
Inserting the values from above and solving the equation:
Psurge = .8 * 50 *125 = 5000 (psi)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
density (lbs/ft^3) = 30
velocity (ft/s) = 85
Entering these values yields:
Psurge = .8 * 30 * 85 = 2040 (psi)
