A closed-cycle gas turbine plant consists of a compressor, a heat exchanger, a heater, a two-stage turbine with reheater, and a cooler. The maximum and minimum pressures and temperature in the cycle are 30 bar and 570oC, and 7.5 bar and 15oC. The pressure in the reheater is 15 bar. Sketch the layout of the plant and indicate pressures and temperatures between the components if (a) the heat exchanger is used, (b) the heat exchanger by-passed.
