How does particle theory explain viscosity

Stokes' law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube. Electronic sensing can be used for opaque fluids. Knowing the terminal velocit… WebExplain what viscosity is; Calculate flow and resistance with Poiseuille’s law; Explain how pressure drops due to resistance; ...

What is Viscosity? Application, Flow, Factors

WebThe particle model has four main tenets: All substances are made of particles. The particles are attracted to each other (some strongly, others weakly). The particles move around (have kinetic energy). As temperature increases, the particles move more (their kinetic energy increases). A solid particle diagram.

WebThe precise definition of viscosity is based on laminar, or nonturbulent, flow. Before we can define viscosity, then, we need to define laminar flow and turbulent flow. Figure 1 shows both types of flow. Laminar flow is characterized by the smooth flow of the fluid in layers that do not mix. Turbulent flow, or turbulence, is characterized by ... Webrelative to) the boundary velocity. This arises because of viscosity, ν, which is a fluid's resistance to flowing, i.e. fluid friction. The fluid literally sticks to the boundary. The higher its viscosity, the more a fluid resists flowing. Honey, for example, has a higher viscosity than water. The kinematic viscosity of water is ν = 0.01 cm2 ...

WebIf a particle only experiences its own weight while falling in a viscous fluid, then a terminal velocity is reached when the sum of the frictional and the buoyant forces on the particle due to the fluid exactly balances the gravitational force. This velocity v (m/s) is given by: [7] (vertically downwards if ρp > ρf, upwards if ρp < ρf ), where: WebViscosity reflects what is happening on the molecular level, and according to the kinetic theory of matter: molecules/ particles are in continual motion. The motion of these particles is dependent on temperature (among other factors) in the form of thermal and kinetic energy, which determines velocity particle travels.

WebThe larger the particle, the slower the Brownian motion will be. Smaller particles are kicked further by the solvent molecules and move more rapidly. An accurately known temperature is necessary for DLS because knowledge of the viscosity is required (because the viscosity of a liquid is related to its temperature). The temperature also needs to be WebIn fluid dynamics, viscosity is the parameter to measure the thickness or thinness of any given fluid. Density is the measure of spaces between two particles in a given fluid. Viscosity and density are the characteristics of a fluid, but there is no direct relation between viscosity and density.
