Air flows reversibly and adiabatically in a nozzle. At section 1 of the nozzle the velocity, pressure, temperature, and area are 165 m/s, 350 kPa, 480 K, and 13 X 10-4 m?. At section 2 in nozzle the area is 26 X 10 4 m2. Find: (a) The mass flow rate in the nozzle. (b) V2, M2, p2, t2 and v2. (Note: There are two independent answers for this condition. Calculate both cases. If there is a throat, determine its area.)
