QUESTION 2 It is proposed to have carbon dioxide (CO2) gas pass through an uninsulated nozzle. The CO2 is to enter at 312 K, 394 kPa, at a velocity of 4 m/s. The CO2 is to exit the nozzle at 374 K, 81 kPa, and a velocity of 129 m/s. The mass flow rate of the CO2 is 0.33 kg/s. The nozzle surface is maintained at 409 K. The rate of entropy generation for the proposed process is kW..... to 4 d.p. Use cold-air standard analysis and Take R= 0.1889 kJ/kgk and Cp=0.846 kJ/kgK Provide unit symbol.
