Velocity of a lubrication system in aircraft design typically refers to the flow velocity of the lubricating fluid (usually oil) as it moves through the system. The formula for velocity (v) is defined as:
- V is the velocity of the lubrication (in meters per second, m/s).
- 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 Lubrication (in square meters, m²).
