this is a thermodynamics question thank you


Extracted text: Example 8.1 Steam generated in a power plant at a pressure of 8,600 kPa and a temperature of 500°C is fed to a turbine. Exhaust from the turbine enters a condenser at 10 kPa, where it is condensed to saturated liquid, which is then pumped to the boller. (a) What is the thermal efficiency of a Rankine cycle operating at these condi- tions? (b) What is the thermal efficiency of a practical cycle operating at these conditions if the turbine efficiency and pump efficiency are both 0.75? (c) If the rating of the power cycle of part (b) is 80,000 kW, what is the steam rate and what are the heat-transfer rates in the boiler and condenser?
