Question

A street underpass has a sag vertical curve. The following data apply: Length of vertical curve = 7 + 5.0 Entering profile grade, g1 = .0.95% Existing profile grade, g2 = +3.75% PVI station = 47+00 PVI elevation = 475.00 ft A drainage inlet must be designed to carry away the stormwater flow at the low point of the vertical curve. Calculate the station and the elevation of the center of the inlet (Calculate the low point station and elevation). From the data in Problem 7 above, determine: The station of the high point The elevation of the high point From the data in Problem 9 above, determine: The Station of the law point The elevation of the Low point
