I have worked in conjunction with Kayti Curtis and Yoon Choi in the creation of MathCad files for sizing the components of the lever arm and the rapid mix tube We have helped to identify all the essential design constraints for the elemenets of the dosing arm and constituent parts. These design parameters include the sizing of the rapid mix orifices to achieve a certain energy dissipation rate, and how to best create the scale on the lever arm. I also assisted in the sizing of the float in the rapid mix tube. I have also been put in charge of creating an excel file for helping to create a acrylic model of the Agalteca plant. I have also conducted experiments in order to determine the constraints on the sizing of the dosing orifice, by conducting clogging experiments to find the nature of the clogs. Please see the "Orifice Clogging Experiment" for further details regarding our experimental results.
