Bingham viscosity
WebNon-Newtonian fluid. A non-Newtonian fluid is a fluid that does not follow Newton's law of viscosity, that is, it has variable viscosity dependent on stress. In non-Newtonian fluids, … WebSince the effective pressure in the capillary is one-half the observed pressure with one arm open to the atmosphere, for the Bingham viscometer F = 1.50 X 10-6 -t- 0.455 X 10-6 log 7. Introducing this correction in Eq. (2), the viscosity at a pressure of one atmosphere is calculated by 7 = CPt C'p FPT. (8) t For convenience 7 is plotted against ...
