Extracted text: 1. In a steam power plant, steam is supplied to the high-pressure turbine at 2800 kPa and 648 K. It is expanded to 558 kPa and sent to the boiler where it is heated to 558 kPa and 648 K. It is then expanded to a final pressure of 2.5 kPa in the low-pressure turbine. Determine: (a) The ideal reheat cycle efficiency (b) The ideal Rankine cycle efficiency in the absence of reheating.
