2. A converging duct has an arca ratio of A /A2 = 2. At A,: M-3, P, -0.2 atm; T; - 200K. A shock wave is at As = 0,568 A. (a) What is M2 and P2? (b) if A2 = 0.2 m² what is the mass flow rate in the duct?: (c) what is the change in entropy AS from state 1 to 2. Approx. Ans: (a) M2 -0.8; P3 -- 2.3 atm; (b) m - 100 kg/s; (c) AS - +210 J/kg
