A power plant taps steam superheated by geothermal energy to540 K(the temperature of the hotreservoir) and uses the steam to do workin turning the turbine ofan electric generator. The steam is thenconverted back into waterin a condenser at 326 K (the temperatureofthe cold reservoir), after which the water is pumped back downintothe earth where it is heated again. The output power (work perunittime) of the plant is 75,500kilowatts.
(a) Determine the maximum efficiency atwhichthis plant can operate.
(b) Determine the minimum amount of rejected heat that mustberemoved from the condenser every twenty-four hours.
