Problem 2: [40 points] For an industrial application, compressed steam at a specified temperature needs to be supplied at a rate of 0.8 kg/s. To this end, a compressor and a constant-pressure heater are employed in series, as shown in the figure below. During the compression process in the compressor, temperature remains constant, and the compression process can be treated as reversible. In the heater, the heat is transferred from a reservoir (source) at 1000 K. Find the following: 1. Specific enthalpy and specific entropy at the inlets and outlets (compressor and heater). 2. Rate of heat transfer and work transfer to the compressor. 3. Rate of heat transfer to the heater. 4. Rate of entropy generation by the processes. Use linear interpolation wherever necessary. Neglect the kinetic and potential energy changes. Provide your final answers in SI units.
