A team power plant operates on an ideal reheat Rankine cycle. The plant maintains the boiler pressure at 17.5 Mpa, the reheater section at 2 Mpa and the condenser at 1 kPa. Steam enters both stages of the turbine at 900 oC. If the mass flow rate is 12 kg/s, determine: a) The total rate of heat input in the boiler; b) The total rate of heat rejected in the condenser; c) The power produced in MW; d) The thermal efficiency of the cycle in %.
