Read the questions carefully before answering. Box or indicate your final answers when solving and draw your diagrams cleanly or use correction tape/fluid. Use the steam tables provided and DO NOT ROUND the values from the steam table. Use 4 decimal places when solving and use 2 decimal places for final answers only. Draw the TS diagram with proper placement and label of points when required. A Steam power plant operates using the actual Rankine Cycle where steam initially enters the turbine at 5.0 MPa and 400C then after an irreversible adiabatic process, it exits the turbine with a dryness of 90. It then condenses at 7 kPa and exits as saturated liquid. Draw the TS diagram, find the thermal efficiency, and steam rate.
