A horizontally laid circular pipe culvert having an elevation of its top to be 26m crosses at right angles under a proposed 120m symmetrical parabolic highway. The point of intersection of the grade lines is at station 5+216 at 27m elevation while that of the culvert is at station 5+228. The backward tangent has a grade of 3% and the grade of the forward tangent is -1.6%. Under this condition, what will be the depth of the cover of the pipe? Find the location of the highest point of this curve referred from PC.
