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