Gas flowing through a converging-diverging nozzle experiences a normal shock, as per graphic A. a. What is the physical meaning/application of this problem in the industry. Explain your assumptions and the equation(s) to be used ( 8 marks) b. Calculate Mach number Ma2 ( 8 marks) c. Caiculate Air velocity u2 ( 9 marks) Assume that: 1. Air is an ideal gas with constant specific heat. II. Flow through the nozzle is steady, one-dimensional, and isentropic before the shock occurs. III. The shock wave occurs at the exit plane. Data: a. air=1.4 b. Rair=0.06855Btu/lbmR, c. Pa=1MPa d. Ta=300K e. Ma11=2.4 Graphic A. Air flowing through converging-diverging nozzle
