In aircraft design and engine performance analysis, velocity (\(V\)) is an essential parameter for understanding the behavior of gases or air within the engine, such as the GE J47. Velocity represents the speed at which these gases are moving. The formula for velocity is defined as:
– \(V\) represents the velocity of the fluid, typically measured in meters per second (m/s).
– \(\dot{m}\) is 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 flows, measured in square meters (m²).
