Question 2 The compressor in a plant (see the figure below) receives carbon dioxide at 100 kPa, 280K with a low velocity. At the compressor discharge the carbon dioxide exits at 1100 kPa. 500 K, with velocity of 25 ms and then flows into a constant-pressure after cooler (heat exchanger) where it is cooled down to 350 K. The power input to the compressor is 50 kW. The table below provides the ideal gas properties of carbon dioxide at 1 bar pressure mass basis. (R=0.1889 kJ/kg-K) (a) What is the enthalpy at the entrance (1) of the compressor? (b) What is the enthalpy at the exit (2) of the compressor (c) What is the work done by the compressor? (d) What is the mass flow rate of carbon dioxide as it passes through the compressor le) What is the enthalpy at the exit (3) of the cooler section? (7) What is the amount of heat transferred in the cooler section? (g) What is the heat transfer rate in the cooler section?
