Air enters an adiabatic chamber steadily at 300kPa, 200 C, and 45 m/s. It leaves at 100 kPa and 180 m/s. The inlet area of the nozzle is 110cm^2. The molar mass is 29 g/mol. Determine the density of the air at the inlet of the nozzle. DeterMine the mass flow rate of air through the nozzle. Knowing the specific enthalpy of air at the inlet is 475 kJ/kg, use energy balance to determine the specific enthalpy of air at the outlet of the nozzle. Calculate the change in specific entropy between the inlet and outlet of the nozzle.
