Asteel pipe carrying engine oil at 250°f (n = 3.2 btu/h-ft-of) loses heat to the outside air at 77 °f with h = 7.9 btu/h- ft. f. the pipe has a 6.0-inch inner diameter and is made of 1/4-inch thick steel (k = 36 btu/h-ft-f), and is 85 ft long. it is coated with a 1/2-inch thick tube of foam insulation (k = 0.013 btu/h-ft-f) to reduce heat loss. a. what is the total rate of heat loss (a) from the oil to the air across the insulated pipe? b. what is the temperature of the outer surface of the steel pipe that touches the foam? c. what would the heat loss be if there were no insulation?
