The mass flow rate of core air, denoted as ṁ refers to the mass of air passing through the engine core of an aircraft engine in a given time. This parameter is an essential factor in aircraft engine design and performance analysis.
The formula for calculating the mass flow rate of core air is:
– ṁ is the mass flow rate of core air (in kilograms per second, kg/s).
– ρ is the density of core air (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area of the core air passage (in square meters, m²).
– V is the velocity of core air (in meters per second, m/s).
