The power meter should include correction for power factor (PF) on AC feeds; otherwise, it will be necessary to also record the power factor in the measurement report. All energy consumption calculations are based on averaging multiple readings over the course of measurements.

c. Suppose the electrical power was supplied by nuclear energy. How much uranium would be needed for your yearly consumption? d. The cost for Uranium Oxide (U3O8), the primary nuclear reactor fuel, is $10.15 per pound or about $0.022 per gram. What would be the cost of the uranium to generate your electricity? e. Coal costs about $24.38 per ton.

2. The Kilowatt Hour, or kWh, is not a unit of power but of energy. Notice that kilowatt is a unit of power and hour is a unit of time. E = P x t (rearranged from above). A kilowatt hour is equal to 1 kW delivered continuously for 1 hour (3600 sec). 1 kWh = 1000 J x 3600 sec = 3.6 x 106 J = 3600 kJ. sec

Peak electrical demand is calculated by identifying the single interval in which the most electrical energy (kWh) was consumed, and calculating the average power consumption during this interval. For example, if 100 kWh were consumed during a 15-minute demand period, the electrical demand during this interval would be:

64. A power plant, having a Carnot efficiency, produces electric power P from turbines that take in energy from steam at temperature Th and discharge energy at temperature Tc through a heat exchanger into a flowing river. The water downstream is warmer by (T due to the output of the power plant. Determine the flow rate of the river. 65.

Therefore, the distortion power calculated using (1.2.10), equals zero independently on the definition for calculating reactive power Q, because Q=0. However, DI, gives quite inaccurate results for linear resistive loads because the nonlinearities of the current are caused entirely by nonlinear voltage supply.
