WebViscosity is represented by the symbol η “eta”, and the use of the Greek letter mu (μ) is also common. Furthermore, viscosity is also known as dynamic viscosity or absolute viscosity. Apart from this, we also deal with … Informally, viscosity is the quantity that describes a fluid's resistance to flow. Fluids resist the relative motion of immersed objects through them as well as to the motion of layers with differing velocities within them. See more Viscosity is first and foremost a function of material. The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to … See more The the mathematical expression describing the flow of fluids in circular tubes was determined by the French physician and physiologist Jean Poiseuille (1799–1869). Since … See more Motor oil is like every other fluid in that its viscosity varies with temperature and pressure. Since the conditions under which most automobiles will be operated can be anticipated, the behavior of motor oil can be specified … See more The mathematical expression describing the viscous drag force on a sphere was determined by the 19th century British physicist George Stokes. I will not derive it here (but I probably should someday in the future). R = 6πηrv … See more

WebThe dynamic viscosity η drops off very quickly for liquids as their temperatures increase. … WebAug 28, 2024 · The moving plane has area A and requires force F to overcome the fluid’s internal resistance. The force necessary to move a plane of area A past another in a fluid is given by Equation 2.6.1 where V is the velocity of the liquid, Y is the separation between planes, and η is the dynamic viscosity. F = ηAV Y. WebViscosity is represented by the symbol η “eta”, and the use of the Greek letter mu (μ) is also common.
