4.108 A simple steam power plant, shown schematically in Fig. 4.44, operates on 8 kg/s of steam. Losses in the connecting pipes and through the various components are to be neglected. Calculate (a) the power output of the turbine, (b) the power needed to operate the pump, (c) the velocity in the pump exit pipe, (d) the heat transfer rate necessary in the boiler, (e) the heat transfer rate realized in the condenser, (f) the mass flux of cooling water required, and (g) the thermal efficiency of the cycle.
