In the context of aircraft design, the cross-sectional area of an auxiliary system refers to the area through which a fluid or substance flows within that system. The formula for cross-sectional area (A) can be defined as:
– Cross-Sectional Area (A) is typically measured in square meters (m²).
– Mass Flow Rate (ṁ) is the rate of mass flow through the system and is measured in kilograms per second (kg/s).
– Density (ρ) is the density of the fluid or substance flowing through the system and is typically measured in kilograms per cubic meter (kg/m³).
– Velocity (V) is the velocity of the fluid or substance and is typically measured in meters per second (m/s).
