WebStep 1/2. Given: A convergent-divergent with an exit area is A 1 = 0.5 m 2. Throat area, A 2 = 0.25 m 2. Inlet reservoir pressure P 1 = 1 a t m, and exit static pressure P = 0.6 a t m. For … This nozzle configuration is called a convergent-divergent, or CD, nozzle. In a CD nozzle, the hot exhaust leaves the combustion chamber and converges down to the minimum area, or throat, of the nozzle. The throat size is chosen to choke the flow and set the mass flow rate through the system.
