Q2: A flocculation tank with a discharge of 50,000 m³/day and alum dosage is 50 mg/1, Gt=4*104 at a temperature of 15 °C. This tank contains three paddles, each paddle has two boards with a dimension of 5m length, rotational speed is 2.5 rpm, and velocity gradient is 30 s¹. The distance between the center of the board and the shaft is 1.25m find: 1)Design this tank if the depth equal one-third of width, assuming depth according to design criteria of flocculation tank 2)Power required Width of the paddles?
