The density of a lubrication system in aircraft design refers to the mass per unit volume of the lubricating fluid or oil used to reduce friction and provide proper lubrication to various components within the aircraft’s engine or machinery. The formula for density (ρ) is defined as:
- ρ = Density of the fluid (in kilograms per cubic meter, kg/m³)
- P = Pressure of the fluid (in pascals, Pa)
- R = Specific gas constant for the fluid (in J/(kg·K))
- T = Temperature of the fluid (in kelvin, K)
