The cross-sectional area (A) of a wet compressor in aircraft design is the area through which air flows. It can be calculated using the following formula:
– A is the cross-sectional area (in square meters, m²).
– ṁ is the mass flow rate of air (in kilograms per second, kg/s).
– ρ is the density of the air (in kilograms per cubic meter, kg/m³).
– V is the velocity of the air (in meters per second, m/s).
