A hydronic piping scope has 28 straight pipe pieces, each 20 ft long. The insulation order includes 5 percent for cuts and fittings. What insulation length should be carried?
Correct Answer
A) 588 ft
Base length is 28 x 20 = 560 ft. Adding 5 percent gives 560 x 1.05 = 588 ft. Other choices omit waste, add only half the allowance, or round to a larger stock number.
