The density ((\rho)) in the context of a GE YF120 or any gas turbine engine represents air density, which is the mass of air per unit volume. Air density varies with altitude, temperature, and pressure and can be calculated using the ideal gas law. The formula for air density ((\rho)) is:
- 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
