An existing rectangular clarifier at a drinking water treatment plant is 18 ft wide and 72 ftlong. It was originally designed for an overflow rate of 600 gpd/ft2 and it is currentlyoperating at its design capacity. Inclined-tube settling bundles are to be added and willoccupy 80 percent of the plan area, inlet flow distribution systems for the retrofitted tubebundles excludes flow through the remaining 20 percent of the surface area. Tubebundles will have a design overflow rate of 5,000 gpd/ft2. Complete an analysis todetermine the present capacity in gal/day, and the increased capacity in gal/day after thetube bundles are installed.

Please help. Show complete solution and avoid truncation. Thank you A steep rectangular channel is to carry flow rate of 1.90 m3/s wirh a slope of 0.01 and roughness coefficient of 0.011, for a minimum area of the material to use, compute: Depth if the channel in m Width of the channel in m Area of the steel material to be used if the channel is 3m
At a wastewaterdischarge point, 2500 L/s of effluent must be conveyedin a straight rectangularchannel at a depth not exceeding 0.55 m. The smooth concrete channelbase is 1.8 m wide.

The bed of a corrugated channel, with Manning’s coeffcient n =0.019 s/m^1/3 drops 25 m every 1500 m. The channel has a semi-circular cross section with total width of W = 10 m (i.e. radius of the semi-circle is 5 m). 1. Given that the stream has a water depth of h = 2.5 m, find the flow rate in the stream 2. A concrete divider with the same Manning’s coeffcient was installed at the middle of the stream. Given that the total flow rate in the stream stays the same, would the water depth in the stream change as a result of the divider? If so, would it increase or decrease? Would the stream velocity change? If so, would it increase or decrease? You may assume the thickness of the divider to be negligible.
