In aircraft design, the cross-sectional area of a control system refers to the measure of the area perpendicular to the direction of the fluid flow (such as air) through the system. The formula for calculating the cross-sectional area (A) is defined as
– Cross-Sectional Area (A) is measured in square meters (m²).
– Mass Flow Rate (ṁ) is the rate at which mass passes through the control system and is measured in kilograms per second (kg/s).
– Density (ρ) is the density of the fluid passing through the control system and is measured in kilograms per cubic meter (kg/m³).
– Velocity (V) is the speed at which the fluid is flowing through the control system and is measured in meters per second (m/s).
