An Apparatus To Measure Capillary Jet Thrusts And The Evaluation Of Normal Stresses In Fluids, Charles Donald Green

Masters Theses

"The purpose of this work was to design, construct and calibrate simple, inexpensive apparatus which could be used to measure the normal stresses and tangential shear stresses of a fluid. For normal stress measurements, the capillary jet thrust principle was selected. A standard analytical balance was modified so that capillary tubes could be fitted on it horizontally. It was designed so that the thrust produced by a jet of fluid from the tube caused a deviation from the zero balance position. The weights needed to rezero the balance gave a measure of the thrust"--Summary, page 1.
