A regenerative cycle with one stage of reheating is executed with steam expanding initially from 20 Mpaa and 540 deg C. The reheater pressure is 10 Mpaa. The steam leaves the reheater at 540 deg C. Steam is bled after reheating to one CFWH and on one OFWH a pressure equal to 5 Mpaa and 1 Mpaa respectively. The CFWH has a Terminal Difference of 4 deg. C. The condensate of the CFWH is routed to the OFWH thru a trap. Condensation occurs at 60 deg C. Sketch the equipment and TS diagram. Isentropic expansion and compression efficiencies are 90 %.Answer the following for 2.5 kg/sec of total steam circulated , and fill up the blanks with your answers in the items below:

1. Equipment and TS diagram of the cycle
