In aircraft design, the mass flow rate of a lubrication system refers to the rate at which lubricating oil or fluid is supplied or circulated through the engine or machinery to reduce friction and maintain proper lubrication. The formula for calculating the mass flow rate (ṁ) in a lubrication system is defined a
- ṁ is the mass flow rate in kilograms per second (kg/s).
- ρ is the air density in kilograms per cubic meter (kg/m³).
- A is the cross-sectional area through which Fuel enters (in square meters, m²).
- V is the velocity of the Fuel entering the engine (in meters per second, m/s).
