- Injector Duty Cycle Calculator

## Injection Pressure Formula

IP = F/PA

Variables:

- IP is the Injection Pressure (psi)
- F is the force (lb)
- PA is the projected area (in^2)

To calculate Injection Pressure, divide the injection force by the projected area.

## How to Calculate Injection Pressure?

The following steps outline how to calculate the Injection Pressure.

- First, determine the force (lb).
- Next, determine the projected area (in^2).
- Next, gather the formula from above = IP = F/PA.
- Finally, calculate the Injection 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.

force (lb) = 400

projected area (in^2) = 700
