The velocity of a turboprop engine in aircraft design refers to the speed at which the exhaust gases exit the engine and pass through the propeller, contributing to thrust generation. 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 the engine (in square meters, m²).
