Enter the differential head (psi) and the suction head (psi) into the Shut Off Pressure Calculator. The calculator will evaluate the Shut Off Pressure.

## Shut Off Pressure Formula

The following two example problems outline the steps and information needed to calculate the Shut Off Pressure.

SOP = 1.2* (DH + SH)

Variables:

- SOP is the Shut Off Pressure (psi)
- DH is the differential head (psi)
- SH is the suction head (psi)

To calculate the shut-off pressure, add the differential head to the suction head, then multiply the result by 1.2.

## How to Calculate Shut Off Pressure?

The following steps outline how to calculate the Shut Off Pressure.

- First, determine the differential head (psi).
- Next, determine the suction head (psi).
- Next, gather the formula from above = SOP = 1.2* (DH + SH).
- Finally, calculate the Shut Off Pressure.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

differential head (psi) = 50

suction head (psi) = 30

SOP = 1.2* (DH + SH)** **= ?
