Example 8: A flocculation basin is designed to treat water of 1 m³/s flow rate. The length of the basin is 30 m and width is 12.25 m and the basin depth is 4.5 m. The basin is provided by four axes (shafts) a long its length, each shafts has two blades, the width of each blade is 0.3 m with 12 m length, the distance between the center of shaft and the center of each blade is 2 m, the coefficient of drag is 1.8, the velocity of blade in the basin 2.5 rpm. use (u = 1.312 * 10-3) N.s/m², p = 1000 Kg/m³. calculate: 1- The power requirement in unit of (KW). 2- Flocculation time in unit of (min). 3- The volume of G of each blade.
