9. Carbon dioxide expands isentropically through a duct from 135 kPa and 110 °Cto 75 kPa and 335 m/s. Compute the (i) exit temperature, (ii) exit Mach number,(iii) inlet velocity

and (iv) inlet Mach number, (v) stagnation temperature, and (vi)stagnation pressure. Determine whether the flow is sonic, supersonic or subsonic at inlet and outlet conditions. For CO2, k= 1.30 and R= 188.9 J/kg.K. (Hint: Watch video Chapter 11-CO2 Isentropic flow.mp4").
