000 100 140 2 00 240 300 Solution1 Change in slope 1 10

- -0+00- 1+00_ 1+40_ 2 +00 2+40 3+00

1) Change in slope = 1 -10 = - 9^o (Slope Reduced by 9^o)

2) Change in elevation from Station 0+00 to1+40 = tan (Angle) * Horizontal distance = (tan 10) *140 = 24.685 feet

3) Length of pipe rom Station 0+00 to1+40 = Horizontal Distance / [Cos (angle)] = 140 / [cos 10] = 142.159 feet
