In an electrically heated home, the temperature of the ground incontact with a concrete basement wall is 13.0oC. The temperatureat the inside surface of the wall is 22.7oC. The wall is 0.19m thickand has an area of 7.4m2. Assume one kilowatt* hour of electricalenergy costs $0.10. How many hours are required for one dollar'sworth of energy to be conducted through the wall?

Answered: In an electrically heated home, the…

Many decisions are made on the basis of the payback period: the time it will take through savings to equal the capital cost of an investment. Acceptable payback times depend upon the business or philosophy one has. For some industries, a payback period is as small as 2 yeas) Suppose you wish to install the extra insulation in the preceding problem. If energy cost $1.00 per million joules and the insulation was $4.00 per square meter, then calculate the simple payback time. Take the average T for the 120-day heating season to be 15.0 .
