Anuclear power plant generates 750 mw of power. the heat engine uses a nuclear reactor operating at 315c as the source of heat. a river is available (at 20c) which has a volumetric flow rate of 165 m/s. if you use the river as a heat sink, estimate the temperature rise in the river at the point where the heat is dumped. assume the actual efficiency of the plant is 60% of the carnot efficiency

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.
