3. Designing a long-rectangular settling basin for type-2 settling: A city must treat about 15000 m/d of water. Flocculating particles are produced by coagulation, and a column analysis indicates that an overflow rate of 20 m/d will produce satisfactory removal at a depth of 3.5 m. Determine the size of the required tank (and dimensions form volume), retention time, and horizontal velocity
