Methane gas at a pressure of 0.69 MPa and an ambient temperature of 26.7 C will be pressed to a pressure of 3.45 MPa by means of a compressor, and at this time its temperature will increase to 182 C. This pressurized gas will then be sent to a cooler, where it will be cooled to 38 C. This system; a) Draw the schematic representation (20 points) b) Do the thermodynamic analysis (30 points) Data: 0.69 MPa ; H26.7 C = 946.7 kJ/kg ; S26.7 C = 6.071 kJ/(kg K) 3.45 MPa ;H182 C = 1324.2 kJ/kg ; S182 C = 6.238 kJ/(kg K) 3.45 MPa; H38 C= 949.6 kJ/kg ; S38 C = 5.264 kJ/(kg K)
