In aircraft design, pressure gauges are commonly used to measure various types of pressure, such as atmospheric pressure, cabin pressure, hydraulic pressure, and more. The formula for pressure (P) and its SI unit in aircraft design is as follows:
This is the difference in pressure between two points. The formula is straightforward:
- P_differential is the differential pressure in Pascals (Pa).
- P1 and P2 are the pressures at the two points being compared in Pa
