The mass flow rate of a reciprocating engine in aircraft design can be calculated based on the engine’s displacement volume, air density, and other operating parameters. The formula for the mass flow rate (ṁ) is as follows
– ṁ = Mass Flow Rate (in kilograms per second, kg/s)
– V_disp = Displacement Volume of the engine (in cubic meters, m³)
– ρ = Density of the air (in kilograms per cubic meter, kg/m³)
– A = Cross sectional area ofEngine speed (in revolutions per minute, RPM, which may need to be converted to seconds)
