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.

The figure to the right gives the schematic of a vapor power plant in which water steadily circulates through the four components shown, The water flows through the boiler and condenser at constant pressure and through the turbine and pump adiabatically and isentropically. Kinetic and potential energy effects can be ignored. Assume mass flow rate is 2 kg/s. Process data is as follows.
