A company is putting in a proposal for a new coagulation water treatment plant. The design flow for the plant is 0.125 m3/s. The average water temperature of the source water is 15°C. The following design assumptions are to be for designing the tank: 1. Number of tanks = 1 (with I backup spare) 2. Tank configuration. circular with liquid depth = 2d (or depth is equal to 2 times the diameter) 3. Detention time = 10 s 4. Velocity gradient = 800 s-1 5. Impeller type: Turbine, 6 flat blades (Np, = 5.7) 6. Available impeller diameters: 0.45, 0.60 and 1.0 m 7. Assume that B = 1/3H In order to design the rapid-mix system, you are asked to determine the following: 1. Water power input in kW 2. Tank dimensions in meters 3. Diameter of the impeller in m 4. Rotational speed of impeller in rpm
