Air flows in a converging duct at the rate m? = 0.25 kg/s. At the location where the area is A1 = 6.5 cm 2 , air pressure is p 1 = 140 kPa, and Mach number is M 1 = 0.6. (a) Find the stagnation temperature. (b) When the flow is choked, what is the size of the throat area? (c) Give the percent reduction in area from station 1 to the throat. (d) Find the pressure at the throat
