The velocity (V) of gases in an airplane turbine engine can be calculated using the following formula:
- V is the velocity in meters per second (m/s).
- ṁ is the mass flow rate of gases in kilograms per second (kg/s).
- A is the cross-sectional area through which air is ingested into the engine in square meters (m²).
- ρ is the density of the air in kilograms per cubic meter (kg/m³).
