1. Determine the slope of the zone settling region (ZSV) (this is the settling velocity for
clarification).
2. Extend the tangents from the ZSV region and compression region and bisect the angle
formed to locate point 1.
3. Draw a tangent to the curve at point 1.
4. Knowns: Co, Ho, and select Cu, then make a mass balance
Cu.Hu = Co.Ho, calculate Hu from:
