Question

A settling column analysis is performed on a dilute suspension of particles from water. The suspension exhibited discrete particle settling characteristics. Data collected from samples taken at a depth of 1.5 meters are as follows:

Time required to settle 1.5 m (min)	0.6	1.2	2.2	4.5	6	8.8
Fraction of Particles Settled	0.3	0.45	0.6	0.7	0.85	0.96

Plot the velocity distribution for the suspension
Find the overflow rate (Q/A) for a settling tank that will give at least 75% removal.
If the flowrate into the settling tank in part b. is 850 m3/hr, please give the dimensions of you settling tank?
Since you will need to address the smaller particles that have passed through this system at some later point, what is the particle size distribution (mass fraction vs. diameter) if we assume the particle density is that of sand (sg = 2.65)
