In aircraft design and engine performance analysis, the velocity of the air or exhaust gases through an engine, such as the General Electric J31, is a critical parameter. It plays a key role in understanding engine performance and aerodynamics
– \(V\) is the velocity of the fluid (air or exhaust gases) passing through the engine, typically measured in meters per second (m/s).
– \(\dot{m}\) represents the mass flow rate of the fluid, measured in kilograms per second (kg/s).
– \(\rho\) is the density of the fluid, measured in kilograms per cubic meter (kg/m³).
– \(A\) is the cross-sectional area through which the fluid is passing, measured in square meters (m²).
