Mr. Smith needed a barn to house his tobacco. He decided to build a barn 56 feet long with three 14-foot sections. The two side sections are three tier poles high and the middle is four tier poles high. He does not need tier poles on the outside because the frame of the barn will serve as a tier pole. The tier poles are placed on a 48-inch center. He will use 3X6s that are 14 feet long for tier poles at $0.92 a board foot.
a. How many tier poles are needed? b. How many board feet are in one tier pole? c. What was the cost of the tier poles?

A 200-ft-long section of a steam pipe whose outer diameter is 4 in passes through an open space at 50°F. The average temperature of the outer surface of the pipe is measured to be 280°F, and the average heat transfer coefficient on that surface is determined to be 6?Btu/h•ft2•°F. Determine (a) the rate of heat loss from the steam pipe and (b) the annual cost of this energy loss if steam is generated in a natural gas furnace having an efficiency of 86 percent and the price of natural gas is $1.10/therm (1 therm = 100,000 Btu).
