Problem 3: Rankine Cycle with reheat (20 points) A Rankine cycle with reheat is shown in Figure 3, as well as the T-s diagram: T boiler pa conds efficiency of the pump is 0.8. The first turbine has water enter at P3=8000 kPa, T3=480°C. The water expands to 700 kPa, undergoes reheat, and then expands again to 8 kPa. The water mass flow rate is 1 kg/hr. The efficiency of the turbines is 0.88, the Take into account the efficiency of the pump and turbines and find the (15 points) (i) Net work generated (ii) The thermal efficiency Sketch the Ts diagram taking into account the efficiency of the pumps and turbines. Repeat the previous analysis without reheat and calculate (5 points) (iv) The net work generated (v) The thermal efficiency
