"A continuous electric current of 2,000 amps is to be transmitted from a generator to a transformer located 200 feet away. A copper conductor can be installed for $5.8 per pound, will have an estimated life of 23 years, and can be salvaged for $0.8 per pound. Power loss from the conductor will be inversely proportional to the cross-sectional area of the conductor. The power loss in one hour may be expressed as 6.222/A kilowatt, where A is the cross-sectional...

Parker County Community College (PCCC) is trying to determine whether to use no insulation or to use insulation that is either 1 inch thick or 2 inches thick on its steam pipes. The heat loss from the pipes without insulation is expected to cost $1.60 per year per foot of pipe. A 1-inch thick insulated covering will eliminate 72 % of the loss and will cost $0.45 per foot. A 2-inch thick insulated covering will eliminate 92 % of the...

Green oak has a density of 60 pounds per cubic foot. A block of this wood is 1 foot long, 2 feet wide and 3 feet deep. Create a spreadsheet which calculates how much the block weighs. Your spreadsheet should use the following techniques: 1) Short equations rather than one long equation 2) Separate inputs, calculations and outputs 3) Use cells which contain the values of the input parameters such as Width, rather than hardcoding the number 2 into a...

Parker County Community College (PCCC) is trying to determine whether to use no insulation or to use insulation that is either 1 inch thick or 2 inches thick on its steam pipes. The heat loss from the pipes without insulation is expected to cost $1.90 per year per foot of pipe. A 1-inch thick insulated covering will eliminate 84% of the loss and will cost $0.35 per foot. A 2-inch thick insulated covering will eliminate 92% of the loss and...
