The density of bypass air in aircraft design represents the mass of air per unit volume within the bypass section of an aircraft engine, particularly relevant for engines with bypass configurations like turbofan engines. The formula for calculating the density of bypass air is derived from the ideal gas law:
- 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)
