The velocity (V) of a GE CF6 engine in aircraft design refers to the speed of the air as it enters or exits the engine. This velocity is a crucial parameter for understanding the engine’s performance. The formula for velocity is:
– V is the velocity of air (in meters per second, m/s).
– ṁ (pronounced “m-dot”) is the mass flow rate of air (in kilograms per second, kg/s).
– ρ (rho) is the air density (in kilograms per cubic meter, kg/m³).
– A is the cross-sectional area through which air flows (in square meters, m²).
