Now plug what you know into the formula and solve for H, the
distance the 56´ elevation is from point A, or 56.8´:
S = V / H
.038 = 0.8” / H
H = 0.8' / .038
= 21.05'
Measure 21.05 from point A to locate the 56´ spot elevation.
Referring to Figure 9.21, find the location of the 96´ spot eleva-
tion. What do you know?
Slope = .05 (5%)
V = 1' which was determined by subtracting 96' from 97'
H = is what you want to calculate
S = V / H
.05 = 1 / H
H = 1 / .05
H = 20'
