1135 pts) An air stream flows in a converging duct from a cross-sectional area of 40 cm² to a cross-sectional area of 20 cm. If T 400 K, P 150 kPa, and V-50 m/s, find m Pa, and T. (Assume steady, one-dimensional, isentropic flow) -1.4 1 Problem 2 (35 pts] An air stream flows in a converging duct from a cross-sectional area of 30 cm² to a cross-sectional area of 20 cm. If inlet temperature, pressure, and velocity are 300 K, 100 kPa, and 100 m/s respectively, find exit Mach #, pressure and temperature. Is the exit throat and if not find the imaginary throat area. Also, describe different ways to make exit as throat and calculate necessary variables needed
