2. Solve Problem #3 from the given Week #2 slide notes, assuming a rectangular shape basin, T=25C=77F for water properties calculation (interpolations), use appendices found online. A pneumatic flocculation basin is to be designed for a flow of 5 mgd. The design criteria for the basin are as follows (NOTE that Por Power equation is different for pneumatic flocculation, please look it up): Detention time = 5 minutes G = 150 sec Lengh-2x Width Depth = 10 ft Diffuser depth = 9 ft Air flow = 4 cm Solve for the following: 1. Basin dimensions 2. Total air flow in ft/min 3. The number of diffusers required
