Q7. A flocculation. Chamber 30 m long, 12 m wide and 4.5 deep is to treat (y) MLD (million liter per day) of water. It is equipped with 12 m long, 0.3 m wide paddles supported parallel to and moved by four horizontal shafts which rotate at a speed of 2.5 rpm. The center line of paddle is 1.8 m from the shaft which is at mid. depth of tank. Two paddles are mounted on each shaft one opposite to the other. If the mean velocity of water is 25% the velocity of paddle, find:- a Power consumption b- Time of flocculation c- Value of G. Kinematic viscosity v = 1.31x 10 m²/sec, CD-1.8 12 m Shaft 1 k 30m 0.3 m. Plan 0.3m 1.95 m, 1.8 m Elevation 4.5 m
