The painted-steel channel of Fig. is designed, withoutthe barrier, for a flow rate of 6 m3/s at a normal depth of1 m. Determine (a) the design slope of the channel and(b) the reduction in total flow rate if the proposed painted steelcentral barrier is installed.
Water at 20°C flows at a depth of 0.4 m with an average velocity of 4 m/s in a rectangular channel. Determine the specific energy of the water and whether the flow is subcritical or supercritical.
A rectangular channel with a bottom width of 7 m discharges water at a rate of 45 m3/s. Determine the flow depth below which the flow is supercritical.
