The velocity of a turboshaft engine in aircraft design refers to the speed at which the exhaust gases exit the engine. This velocity can be calculated using the following formula:
– V is the velocity of the air entering the engine (in meters per second, m/s).
– ṁ is the mass flow rate (in kilograms per second, kg/s).
– ρ is the air density (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area through which air enters , m/s)
