## About Differential Pressure Calculator (Formula)

The Differential Pressure Calculator you’ve requested uses a straightforward formula to calculate the differential pressure ($dP$) between two applied pressures. The formula is as follows:

**dP=AP1−AP2**

Where:

- $DP$ represents the differential pressure, which is the difference between the two applied pressures.
- $AP1$ stands for Applied Pressure 1, typically measured in pounds per square inch (psi).
- $AP2$ stands for Applied Pressure 2, also measured in pounds per square inch (psi).

This calculation simply subtracts the second applied pressure (AP2) from the first applied pressure (AP1) to determine the differential pressure. Differential pressure measurements are often used in various fields, including fluid mechanics, engineering, and instrumentation, to assess pressure differences between two points. It can be a critical parameter in systems where maintaining specific pressure differentials is important for safety or performance reasons.
