In aircraft design and turbofan engine analysis, the pressure difference (ΔP) typically refers to the change in air pressure across the compressor of the engine. It represents how much the air pressure increases as it passes through the compressor. Here’s the formula, definition, and SI unit for pressure difference in this context:Formula:
The formula for pressure difference (ΔP) is calculated as follows:
- ΔP is the pressure difference in Pascals (Pa).
- P2 is the air pressure at the compressor outlet in Pascals (Pa).
- P1 is the air pressure at the compressor inlet in Pascals (Pa).
