Rankine Cycle: ConcepTest and Example Problem

Try to answer this ConcepTest and solve this example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. By the end of this module, you should be able to answer these on your own. Answers will be given later in this module.

A sample problem on the Rankine Cycle.
Example Problem 1

Steam generated at a power plant at 8.0 MPa and 500.°C is fed to a turbine. Exhaust from the turbine enters a condenser at 15 kPa where it is condensed to a saturated liquid, which is then pumped to the boiler. What is the thermal efficiency of a Rankine cycle with a reversible adiabatic turbine operating at these conditions?
