This digital experiment was created in the Department of Chemical and Biological Engineering, at University of Colorado Boulder for LearnChemE.com by Neil Hendren under the direction of Professor John L. Falconer and Michelle Medlin. It was prepared with financial support from the National Science Foundation (DUE 2336987 and 2336988) and is based on a Fluid Mechanics experimental kit and accompanying worksheet protocol developed with separate support under NSF 1821578 led by Washington State University.
