01) Water is flowing in three side-by-side pipes of diameter (1.8m) each. The Manning's (n) and the bed slope of each pipe are (0.017) and (1:1000) respectively. The water depth in each pipe is (1.6 m). After the development, the discharge above is expected to increase by (25%), and the engineers have decided to replace the three pipes by a trapezoidal channel. The new channel should have (n= 0,013) with the same bed slope , B = 1.15 y, and z=1. Design the cross section of the new channel.

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.
