The density (ρ) in the context of a GE CF34 or any gas turbine engine in aircraft design represents the mass of air per unit volume and is typically referred to as air density. Air density is a function of altitude, temperature, and pressure. It can be calculated using the ideal gas law, which relates these variables.
The formula for air density (ρ) is as follows:
– ρ is the air density (in kilograms per cubic meter, kg/m³).
– P is the atmospheric pressure (in pascals, Pa).
– R is the specific gas constant for dry air (approximately 287.05 J/(kg·K)).
– T is the absolute temperature (in kelvin, K).
