An ideal Rankine cycle with two reheaters is shown in Fig. 8.34. Low pressure is 10 kPa, high pressure is 10 MPa, and the high temperature is 600°C. The first reheater heats 2 MPa steam to 500°C, and the second reheater heats 200 kPa steam to 400°C. For a mass flux of 20 kg/s, show the cycle on a T-s diagram and then determine:
i) The heat added during the first reheat process
ii) The heat added during the second reheat process
iii) The total heat added to the power cycle
iv) The work output of the turbine
v) The state of the steam leaving the turbine
vi) The pump horsepower
vii) The cycle efficiency
