1. (60 points) Steam generated in a power plant at a pressure of 8700 kPa and a temperature of 550 C is fed to a turbine. Exhaust from the turbine enters a condenser at 20 kPa, where it is condensed to saturated liquid, which is then pumped to the boiler. (a) (10 points) Draw this cycle on a TS diagram and explain each of the steps (b) (20 points) What is the thermal efficiency of a Rankine cycle operating at these conditions? a (c) (20 points) What is the thermal efficiency of a practical cycle operating at these conditions if the turbine efficiency is 0.7 and the pump efficiency is 0.8? (d) (10 points) Describe two ways that you can increase the thermal efficiency of a closed-cycle gas- liquid engine
