In aircraft design and engine performance analysis, the mass flow rate (\( \dot{m} \)) is a crucial parameter, especially when considering engines like the GE J47. Mass flow rate represents the amount of mass passing through a specific point in the engine per unit of time. It’s often used to evaluate engine performance. The formula for mass flow rate is defined as:
– \( \dot{m} \) represents the mass flow rate, typically measured in kilograms per second (kg/s).
– \( \rho \) is the density of the fluid passing through the point, measured in kilograms per cubic meter (kg/m³).
– \( A \) is the cross-sectional area through which the fluid flows, measured in square meters (m²).
– \( V \) is the velocity of the fluid, measured in meters per second (m/s).
