You have been asked to provide a design for a rapid mix tank at a water treatment plant which has an average water temperature of 50°F. The tank is to have a detention time (ta = HRT) of 1.5 seconds, a mixing intensity (G) of 2,000/second, and treat a flow (Q) of 10 mgd. a. Identify the volume of reactor required (in ft and gallons) b. Find the reactor dimensions (i.e., Depth and Diameter, in feet) if the rapid mix tank is cylindrical with a depth 2x the basin diameter. Calculate the water power required (in HP) to achieve the desired mixing. d. If motors are available with an efficiency of 68%, what motor power is required (in HP)? с.

Q- To complement the construction of a wall or to connect a wall to be constructed with a previously constructed wall specially If the wall is to be connected vertically when It is left without completion, and each row is an apostate from the row under of it about a quarter or half a brick. The wall is left before it is completed, it is left in the place where each brick stops on the length. It stands out by a quarter of its length from the brick on the head at the bottom, and thus the wall is saw-toothed. The previously built wall each brick is left on the head so that it will down away from the face of the wall about quarter brick and this works done between row and row. The thickness of an existing wall is to be exceed, it will be drilled with dimensions of 1/2x2x2 bricks per square meter of the wall. Non of them
