For each problem, show the details of your calculations (equations, units etc.). Problem #1 A nearly horizontal channel has a bottom width of 3 ft, and it carries a discharge of 60 cfs at a depth of 4 ft. Determine the magnitude and direction of the hydrostatic pressure force exerted on each of the sidewalls per unit length of the channel if: (a) The channel is rectangular with vertical sidewalls (b) The channel is trapezoidal with each sidewall sloping outward at a slope 2 horizontal over 1 vertical, that is m = 2. Problem #2 Determine the average cross-sectional velocity V and the discharge Q for the compound channel shown below: 1m V1=0.5 m/s 20m 3m 4m V2=1.5 m/s V3= 0.3 m/s -22m Problem #3 Determine the rate of momentum transfer and the rate of kinetic energy transfer for the compound channel shown in Problem #2.
