Consider a steam power plant that operates on the ideal reheat Rankine cycle. The plant maintains the boiler at 17.5 MPa, the reheater at 2 MPa, and the condenser at 50 kPa. The temperature is 550°C at the entrance of the high-pressure turbine, and 300°C at the entrance of the low-pressure turbine. Determine the thermal efficiency of this system. Use steam tables. The thermal efficiency of this system is 74 %.

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.

Consider a steam power plant that operates on the ideal reheat Rankine cycle. The plant maintains the boiler at 8000 kPa, the reheat section at 1000 kPa, and the condenser at 20 kPa. The mixture quality at the exit of both turbines is 90 percent. Determine (a) the temperature at the inlet of each turbine, (b) the cycle's thermal efficiency, efficiency of this cycle. Assume a source temperature of 1500 K and a sink temperature of 295 K. (d) the second-law

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. Determine the thermal efficiency of the cycle. The thermal efficiency of the cycle is 59.6 %.
