A storm pipe run of 216 ft must fall at 1/8 in. per ft. What total fall is required?
Correct Answer
A) 27.0 in.
216 feet × 1/8 inch per foot = 27 inches. In feet this is 2.25; 2.25/216 × 100 ≈ 1.04% slope. Dividing an inch drop directly by a foot run does not produce a valid percent. The supplied slope is a design input, not a universal storm-drain minimum.
Why This Is the Correct Answer
216 feet × 1/8 inch per foot = 27 inches. In feet this is 2.25; 2.25/216 × 100 ≈ 1.04% slope. Dividing an inch drop directly by a foot run does not produce a valid percent. The supplied slope is a design input, not a universal storm-drain minimum.
