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 800 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 %. hl (kJ/kg) Format : 92.909 vl (m3/kg) Format : 0.004 wp_in (kJ/kg) Format: 26.7 h2 (kJ/kg) Format: 66.8 h3 (kJ/kg) Format: 3042.6 s3 (kJ/kgK) Format : 6.2589 h4 (kJ/kg) Format : 3592.69 h5 (kJ/kg) Format : 8895.8 s5 (kJ/kgK) Format : 5.6929 x6 Format : 0.2684 h6 (kJ/kg) Format : 2855.7 Qin (kJ/s) Format : 62707 Qout (kJ/s) Format : 62282 W (MW) Format: 89.04 Efficiency (%) Format: 54.5 A team power plant operates on an ideal reheat Rankine cycle.
