dispersions. Non-Newtonian fluids are those where the viscosity varies as a function of the applied shear rate or shear stress. It should be noted that fluid viscosity is both pressure and temperature dependent, with viscosity generally increasing with increased pressure and decreasing temperature.

Ask students if they know the definition of viscosity (viscosity is a measure of resistance to flow; more viscous substances offer more resistance. Composite Volcanoes are the type of volcanoes that are made up of several different intermediate rocks that make up composite volcanoes. Volcanic eruptions at these volcanoes are usually intense due to the viscosity of the lava. The viscous lava hardens on the surface of the volcano and forms steep slopes as it cannot go down the flanks.Jun 04, 2016 · Viscosity is defined as the resistance to flow! Viscosity is often referred to as the thickness of a fluid. You can think of water (low viscosity) and honey (high viscosity). However, this definition can be confusing when we are looking at fluids with different densities. At a molecular level, viscosity is a result the interaction between the ... Viscosity is the measure of a substance's resistance to motion under an applied force. The formula for measuring viscosity is fairly simple: viscosity = shear stress / shear rate.
