A compressor and condenser are used to prepare propane for liquefied storage. First, propane gas enters the isothermal compressor at 0.1 MPa and 20 C (State 1) and leaves as a saturated vapor at 0.84 MPa (State 2). The propane then passes through the isobaric condenser, exiting as a saturated liquid (State 3). To achieve isothermal compression, the compressor must be actively cooled at a rate of 30 kW. Both the compressor and condenser operate steadily at 0.2 kg/s with negligible kinetic and potential energy effects. Use the table below for enthalpy and entropy values at States 1-3: 1 = 622.00 2 = 595.95 3 = 251.64 1 = 2.8187 2 = 2.3544 3 = 1.1799 Draw and label the two processes (State 12, State 23) on (a) a - diagram and (b) a - diagram. (c) Find the power draw of the compressor in kW and (d) the separate rates of entropy generation in the compressor and condenser in kW/K. Do their signs / magnitudes match what you expected to find?
