H311 Liquid Sedimentation Apparatus Hydrodynamics Lab Equipment Didactic Equipment
LIQUID SEDIMENTATION APPARATUS
The bench-mounting apparatus consists of five long, transparent sedimentation columns mounted on a rigid frame.
The rear panel is translucent, with back lighting to improve observation of settling sediments in the columns. The columns are removable for filling before tests. A graduated scale on the rear panel allows students to measure settlement depth.
Supplied with the equipment is a stopwatch to find settling times, a specific gravity bottle, measuring beakers and five rubber bungs. The rubber bungs seal the ends of the columns when the students shake the liquid and particles (slurry) before an experiment.
LEARNING OUTCOMES
• Comparison of settling characteristics of different sediments
• Determination of the effect of concentration on settling characteristics (hindered settlement)
• Determination of velocity distribution curves
• Comparison of flocculent and particle suspensions
• Determination of particle size distribution (grading curve) by liquid sedimentation
