Determine the uniform flow depth in a trapezoidal channel with a bottom width of 8 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 100 ft3/s. Manning roughness factor is 0.015 and the channel bottom slope is 0.004.
A sample of clay was obtained from a point below the water table. An oven-drying test performed on this sample resulted in the following data: Mass of can= 10.88 g Mass of can + wet soil = 116.02 g
The small sphere of mass (m) is suspended initially at rest by the two wires. If one wire is suddenly cut, determine the ratio (k) of the tension in the remaining wire immediately after the other wire is cut to the initial equilibrium tension.
Given the following data for a vertical curve of a road; G1=-2.5%, G2=+5.5% and station of PVI=250+50.At station 252+50, the vertical curve must intersect an existing road at elevation 48.48ft. the elevation on the tangent section at station 256+5..
Calculate the pressure, and the piezometric head at the free surface, at both interfaces, and at the tank bottom. Take the elevation datum at the bottom of the tank.
