Question A3 a. Carbon dioxide enters an adiabatic nozzle steadily at 1 MPa and 500 °C with a mass flow rate of 6000 kg/hr and leaves at 1000 kPa and 450 m/s. The inlet area of the nozzle is 40 cm². Determine the inlet velocity and exit temperature of the CO2. [60%] Answer: inlet velocity = 60.8 m/s, 686.8K b. A closed system containing 2 kg of air undergoes an isothermal process from 600 kPa and 200°C to 80 kPa. Determine the initial volume of this system and the energy transfer within the process. (40%) Answer: Vol = 0.4525m?, 547.1k
