2. In an ideal reheat cycle, steam is generated at 6.3 MPaa,
450°C and partially expands to 0.84 MPaa. At this point, the
steam is withdrawn and passed through a reheater. It re-
enters the turbine at 0.84 MPaa and 480°C. Complete
expansion now occurs to the condenser pressure of 0.2
MPaa. Find the following: (a) the enthalpies at each point, (b)
