## Driving Pressure Calculator

The Driving Pressure Calculator is a tool used to calculate the driving pressure in a fluid system. The driving pressure represents the pressure difference that propels the flow of fluid through a pipe or channel. It is a critical parameter in fluid dynamics and is often used to analyze and design fluid systems.

### Formula

The formula to calculate driving pressure is:

**Driving Pressure = P1 – P2**

where P1 is the pressure at the starting point of the flow and P2 is the pressure at the endpoint of the flow.

### Example

If the pressure at the starting point is 100 psi and the pressure at the endpoint is 80 psi, the driving pressure would be:

Driving Pressure = 100 psi – 80 psi = 20 psi
