Asteam power plant operates on the ideal reheat rankine cycle. steam enters the high-pressure turbine at 8 mpa and 600 oc and leaves at 3 mpa. steam is then reheated at constant pressure to 500 oc before it expands to 20 kpa in the low-pressure turbine. determine: a) the turbine work ouput in kj/kg; b) the thermal efficiency of the cycle (%)
