A reheat-regenerative rankine cycle operates on a turbine efficiency of 95% and pump efficiency of 95%. Boiler pressure is at 15MPa. Reheat occurs at 10MPa. extractions occur at 5MPa and 2MPa for open feedwater heaters. These extractions occur after the expansion after reheating. Steam leaves the boiler and reheater at 600C. Condenser pressure is at 10kPa. SOLVE FOR: a.) Determine the Heat rejected from this cycle per kilogram of steam passing through the boiler(kJ/kg) b.)
