An ideal reheat Rankine cycle with water as the working fluid operates the boiler at
15 MPa, the reheater at 1,200 kPa, and the condenser at 10 kPa. Figure 2 shows the
schematic of the cycle in sequential order. The temperature is 550 °C at the entrance of the
high pressure (High-P) and low pressure (Low-P) turbines. If the mass flow rate through
the cycle is 3 kg/s. For eycle;
i)
sketch T-s diagram,
ii)
calculate the enthalpy (h) value at all indicated locations in the Figure 2,
iii)
determine the net power produced by the cycle,
iv)
determine the rate of heat transfer into the cycle, and
v)
evaluate the thermal efficiency of this system.
