Q2 Figure 2 shows the T-s diagram for a steam power plant operating on the actual Rankine cycle with 3 stages of expansion processes and 2 stages of reheating processes. Important conditions for all states are given in the diagram. By referring to the T-s diagram, determine: (a) Steam quality at the end of the expansion process. (3 marks) (b) Total work output. (c) Total amount of heat addition. (d) Thermal efficiency of the steam power plant. 15 MPa T (°C)A 4 MPa 550.0 500.0- 450.0 330.0 300.0 100.0 91.78 2 MPa ⑦ 7.3594 (12 marks) 75 kPa (6 marks) (4 marks) (kJ/kg.°C) Figure 2 T-s Diagram for Actual Rankine Cycle with 3 Stages of Expansion Processes and 2- Stages of Reheating Processes.
