A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 3 MPa in the boiler and 30 kPa in the condenser. If the quality at the exit of the turbine cannot be less than 85 percent, what is the maximum thermal efficiency this cycle can have?

A steam Rankine cycle operates with a condenser temperature of 30°C, and a boiler pressure of 15MPa. The turbine is divided into two stages, a high-pressure turbine, and a low pressure turbine. In between the turbine stages the steam is reheated by the boiler so that the inlet temperature to both turbine stages is the same. The exit pressure of the first turbine stage is 7MPa. The condenser inlet is a saturated vapor and the outlet a saturated liquid. What is the net work of the cycle? What is the thermal efficiency of the cycle?

Consider a 210-MW steam power plant that operates on a simple ideal Rankine cycle. Steam enters the turbine at 10 MPa and 500°C and is cooled in the condenser at a pressure of 7.5 kPa.   Show the cycle on a T-s diagram with respect to saturation lines.
