Chapter 5, Problem 130P

Some young engineers at the local electrical utility are debating ways to lower operating costs. They know that if they can reduce losses, they can lower operating costs. The question is whether they should design for maximum power transfer or maximum efficiency, where efficiency is defined as the ratio of customer power to power generated. Use the model in Fig. P5.130 to analyze this issue and justify your conclusions. Assume that both the generated voltage and the customer load are constant.

Two DC houses are connected to 200VDC network. The first house operates only for 10 hours per day and consumes a constant current of 20A. The second house operates for 12 hours per day and consumes a constant current of 30A. Find the following: 1- a) Draw the daily power profile for each house. b) The monthly bill for each house if the cost of the kWh is SR 0.10. c) The total energy supplied by the network per month. d) The resistance that is equivalent to the load of each house during the operating time.
A 1500 W heating elements at an initial temperature of 15 C is connected to supply voltage of 115V. After the temperature of the element has stabilized steady state condition it is found that the voltage of 125V is required to maintain the rated output. If the temperature coefficient at 15C of the element is 0.0006 per C determine the element of the final temperature.
