A symmetric compound channel in over bank flow has a main channel with a bottom width of 30 m, side slopes of 1:1, and a flow depth of 3m. The floodplains on either side of the main channel are both 300m wide and flowing at a depth of 0.5m. The mean velocity in the main channel is 1.5 m/s, while the floodplain flow has a mean velocity of 0.3m/s. assuming that the velocity variation within the main channel and the floodplain subsections is much smaller than the change in mean velocities between subsections, find the value of the kinetic energy correction coefficient.
An object is thrown downward from a 150-ft cliff with a velocity of 45m/hr so that it makes an angle of 60° with vertical face of the cliff.
A constant head permeability test was conducted on a clean sand sample. The diameter and length of the test specimen were 10 cm and 12 cm respectively.
In that season, what are the hydraulic radius of the river, its mean velocity and volumetric discharge?
The first pipe of 0.4-m diameter is 500 m long, the second pipe 600 m long, size 0.3 m, and the last pipe is 500 m long of diameter 0.2 m. If the elevation difference between two reservoirs is 30 m, calculate equivalent pipe size and flow in the p..
