Cross-sectional area in the context of a lubrication system in aircraft design refers to the area through which the lubricating fluid (usually oil) flows. It plays a crucial role in determining the flow characteristics of the lubrication system. The formula for the cross-sectional area (A) can be defined as:
- A is the cross-sectional area through which Lubrication (in square meters, m²).
- 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).
