A Simple Viscometer for High School and First Years Undergraduate Program Students: Theory and Experiment
arXiv:1310.7196
Abstract
A simple viscometer consists of mineral water bottle and trink straw is used to predict vicosity of water. A model is derived from Bernoulli's principle and Poiseulli's law. Value about 0.374 - 0.707 cP is obtained for observation in room temperature. About 10 minutes of observation time is needed to get the data. Keywords: equation of continuity, Bernoulli's equation, viscosity coefficient, Poiseulli flow.
