In continuum mechanics, a power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid. This mathematical relationship is useful because of its simplicity, but only approximately describes the behaviour of a real non-Newtonian fluid.
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
The Ostwald and de Waele equation can be written in a logarithmic form: log ( τ ) = log ( K ) + n log ( γ ˙ ) {\displaystyle \log(\tau )=\log(K)+n\log \left({\dot {\gamma }}\right)} The apparent viscosity is defined as η = τ γ ˙ {\displaystyle \eta ={\tau \over {\dot {\gamma }}}} , and this may be plugged into the Ostwald ...
Blood–gas partition coefficient, also known as Ostwald coefficient for blood–gas, [1] is a term used in pharmacology to describe the solubility of inhaled general anesthetics in blood. [2]
Armand Michel A. de Waele FRIC FInstP (17 November 1887 – December 1966) was a British chemist, noted for his contributions to rheology, and after whom the Ostwald–de Waele relationship for non-Newtonian fluids is named. [1] De Waele was born in Islington, London, in 1887, the son of a Belgian father and French mother.
Friedrich Wilhelm Ostwald (German: [ˈvɪlhɛlm ˈɔstˌvalt] ⓘ; 2 September [O.S. 21 August] 1853 – 4 April 1932) was a German chemist and philosopher.Ostwald is credited with being one of the founders of the field of physical chemistry, with Jacobus Henricus van 't Hoff, Walther Nernst and Svante Arrhenius.

The Ostwald–Folin pipette, developed by Wilhelm Ostwald and refined by Otto Folin, is a type of volumetric pipette used to measure viscous fluids such as whole blood or serum. [7] [8] Combustion pipette
The Center for Veterinary Medicine (CVM) is a branch of the U.S. Food and Drug Administration (FDA) that regulates the manufacture and distribution of food, food additives, and drugs that will be given to animals. These include animals from which human foods are derived, as well as food additives and drugs for pets or companion animals.
