The density (ρ) of air entering a CFM (CFM International) engine inlet is a fundamental parameter in aircraft design and engine performance analysis. The formula for air density is defined as follows:
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- P = Pressure of the fluid (in pascals, Pa)
- R = Specific gas constant for the fluid (in J/(kg·K))
- T = Temperature of the fluid (in kelvin, K)
