The system detailed on the main page was used as the bench-scale apparatus to test plate settler performance. The Spring and Summer 2010 team chose tube diameters of 6.35 mm (1/4"), 9.53 mm (3/8"), 12.7 mm (1/2"), 15.875 mm (5/8"), with a 25.4 mm (1") control case for "successful" performance. All tubes were thought to be fixed at a capture velocity of 0.12 mm/s; however, an error in the model resulted in the team switching the fixed capture velocity value to 0.1 mm/s in order to salvage data. A more detailed explanation of the theory, model error, results, and future plans is included in the Final Reflection Report. The procedure followed by the team in designing this experiment can also be viewed in the final reflection report or on the Spring 2010 page, Exploring the Effects of Velocity Gradients on Settler Performance.
A corrected velocity gradient model and materials list is provided.
