Discussion problem: the ideal regenerative rankine cycle with an open feedwater heater uses water as the working fluid. the turbine inlet is operated at 500 psia and 600of and the condenser at 5 psia. steam is supplied to the open feedwater heater at 40 psia. determine the work produced by the turbine, the work consumed by the pumps, the heat rejected in the condenser for this cycle per unit of flow through the boiler

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.
