2. Non-Newtonian fluid - Wikipedia

   en.wikipedia.org/wiki/Non-Newtonian_fluid

   In physics and chemistry, 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 particular, the viscosity of non-Newtonian fluids can change when subjected to force.

3. Dilution (equation) - Wikipedia

   en.wikipedia.org/wiki/Dilution_(equation)

   The basic room purge equation can be used only for purge scenarios. In a scenario where a liquid continuously evaporates from a container in a ventilated room, a differential equation has to be used:

4. Mixture - Wikipedia

   en.wikipedia.org/wiki/Mixture

   [8] [9] Mixtures differ from chemical compounds in the following ways: The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation. There is little or no energy change when a mixture forms (see Enthalpy of mixing). The substances in a mixture keep their separate properties.

5. Miscibility - Wikipedia

   en.wikipedia.org/wiki/Miscibility

   Diesel fuel is immiscible in water.The bright rainbow pattern is the result of thin-film interference.. Miscibility (/ ˌ m ɪ s ɪ ˈ b ɪ l ɪ t i /) is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution).

6. Viscosity models for mixtures - Wikipedia

   en.wikipedia.org/wiki/Viscosity_models_for_mixtures

   In a fluid mixture like a petroleum gas or oil there are lots of molecule types, and within this mixture there are families of molecule types (i.e. groups of fluid components). The simplest group is the n-alkanes which are long chains of CH 2-elements. The more CH 2-elements, or carbon atoms, the longer molecule. Critical viscosity and critical ...

7. Mixing (physics) - Wikipedia

   en.wikipedia.org/wiki/Mixing_(physics)

   Mixing in a ball of colored putty after consecutive iterations of the Smale horseshoe map (i.e. squashing and folding in two). In physics, there are several distinct notions of mixing, all of which try to capture the common-sense notion of mixing, but using rather disparate formal methods, techniques and definitions.
