The falling needle density meter/viscometer (FNDV) consists of a vertical cylinder which is filled with the test sample. Using a needle launcher at the top of the cylinder, the first needle having a known density is allowed to fall through the liquid

Numerical solutions are presented for fully developed laminar flow for a modified power law fluid (MPL) in a rectangular duct. The solutions are applicable to pseudoplastic fluids over a wide shear rate range from Newtonian behavior at low shear rate

This paper reports on a numerical study of the drag force on a sphere moving at constant velocity in inelastic non-Newtonian fluids. The intended application of this work is in the use of the falling ball viscometer to determine flow curves for these

A capillary tube viscometer is described that dispenses with direct pressure measurements by comparing capillary tube flow rates of a fluid whose viscous properties are unknown and a standard Newtonian fluid. Since only flow rate measurements are nee

An implicit finite difference method was applied to analyze laminar natural convection in a vertical channel with a modified power law fluid. This fluid model was chosen because it describes the viscous properties of a pseudoplastic fluid over the en

The use of data from the falling needle viscometer to determine the rheological properties of purely viscous non‐Newtonian fluids is described. From the solution of the basic flow equation, which is given in tabular and graphical form, a method is
