Anuclear-fueled electric power plant utilizes a so-called "boiling water reactor." in this type of reactor, nuclear energy causes water under pressure to boil at 310° c (the temperature of the hot reservoir). after the steam does the work of turning the turbine of an electric generator, the steam is converted back into water in a condenser at 44° c (the temperature of the cold reservoir). to keep the condenser at 44° c, the rejected heat must be carried away by some means-for example, by water from a river. the plant operates at three-fourths of its carnot efficiency, and the electrical output power of the plant is 1.14 109 watts. a river with a water flow rate of 9.50 104 kg/s is available to remove the rejected heat from the plant. find the number of celsius degrees by which the temperature of the river rises.
