Air Bows throagh a coeverging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations in the system. Solve using equations rather than with the tables Note: The specific beat ratio and gas constant for air are given as k-14 and R-0287 kJkg-K respectively Inlet Temperature: TI (K) 367 Inlet pressure: Pl (Pa)-469 Inlet Velocity: VI (m/s)-96 Area at norzle inlet: Al (cmA2) 8.59 Throat area: A (em*2)-3.76 Area at diffuser exit: A (em2) 647 a) Determine the Mach number at the inlet.
