Pipe Pressure Formula
The following formula is used to calculate the Pipe Pressure.
Ppipe = (2*S*T/D)
- Where Ppipe is the Pipe Pressure (psi)
- S is the allowable stress (PSI)
- T is the wall thickness (in)
- D is the outside diameter (in)
How to Calculate Pipe Pressure?
The following example problems outline how to calculate the Pipe Pressure.
Example Problem #1
- First, determine the allowable stress (PSI). In this example, the allowable stress (PSI) is given as 10 .
- Next, determine the wall thickness (in). For this problem, the wall thickness (in) is given as 5 .
- Next, determine the outside diameter (in). In this case, the outside diameter (in) is found to be 3.
- Finally, calculate the Pipe Pressure using the formula above:
Ppipe = (2*S*T/D)
Inserting the values from above and solving yields:
Ppipe = (2*10*5/3) = 33.33 (psi)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
allowable stress (PSI) = 100
wall thickness (in) = 7
outside diameter (in) = 8
Enter these given values yields:
Ppipe = (2*100*7/8) = 175 (psi)
