Measurement Laboratory No. 3 EGR 1011 Fluid mechanics : Stokes Law and ViscosityMeasurement LaboratoryInvestigation No. 3 Scott A. Shearer, ProfessorJeremy R. Hudson, Graduate Teaching AssistantBiosystems and Agricultural Engineering1. IntroductionThis laboratory investigation involves determining the Viscosity and mass density ofan unknown Fluid using Stokes Law. Viscosity is a Fluid property that provides anindication of the resistance to shear within a Fluid . Specifically, you will be using afluid column as a viscometer. To obtain the viscometer readings you will use astopwatch to determine the rate of drop of various spheres within the Fluid . You willdetermine both density and Learning OutcomesOn completion of this laboratory investigation students will: Appreciate the engineering science of ' Fluid mechanics .
fluid using the average velocity of the three spheres. A common unit of viscosity is the Poise, or 1 g/cm.s. 8) Calculate the Reynold’s Number using the fluid and ball properties determined above. Part II: Predict the fall time of similar size spheres of differing materials:
