Extracted text: Exercise-2 A surface water treatment plant is to process 30000 m/d for a large city. A cubic rapid mixing tank will be used to blend 35 mg/L of alum solution with the flow during a detention time of 2 minutes. The solution temperature is 22AC with a viscosity of 9.6 x 104 kg/m/s. Determine the following: a) Quantity of alum coagulant added (kg/day). b) Tank dimensions. c) Power input (kW) necessary for a velocity gradient (G) of 900 s. G =V(P/ uV) Q= V/t
