relationship between viscosity and its chemical constitution?

Question

it is under the topic of viscosity. and i need agraduate level answer.

Answer 1

The streaming toxicological distinction of biophysical stimmulus in reference to the revolution of the spherical connectivity of the nucleus derivitive of the chemical constitution of the viscosity balance of shared derived derivitives.

Answer 2

Viscosity is a measure of the resistance of a fluid to deform under shear stress. It is commonly perceived as "thickness", or resistance to pouring. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. All real fluids (except superfluids) have some resistance to shear stress, but an idealized fluid which has no resistance to shear stress is known as an ideal fluid .

In many situations, we are concerned with the ratio of the viscous force to the inertial force, the latter characterised by the fluid density ρ. This ratio is characterised by the kinematic viscosity.
Chemical composition and viscocity are inter-related.
more dense liquid mean more viscocity. pumping of more viscous liquids requires positive displacement pump.
Viscosity is a property of fluid which affects its behavior. If a fluid is defined as being a substance undergoing continuous deformation when subjected to a shear stress, then the consistency can be termed as the resistance offered by the fluid to such deformation. If static pressure and temperature are fixed, the consistency is constant for gases and Newtonian lifquids and is called absolute viscosity. The consistency of non-Newtonian fluids varies even though the static pressure and temperature are fixed,a function of the applied shear stress. In some cases, the consistency may vary with duration of the applied shear stress. The consistency of non-Newtonain fluids is frequently expressed in terms of apparent viscosity. Thus, the viscometer is an instrument which measures consistency of gases, and Newtonian and non-Newtonian fluids.

Answer 3

Viscosity is the resistance to flow. It is affected by temperature.Decrease in temp means increase in viscosity or vice versa. Other term is it is the ratio of shear stress to shear rate.The SI unit are kg/(m.s) or Pa s (pascal second) The cgs unit is poise; 1 Pa s = 10 poise or 1000 centi poise(cP) or 0.672 lbm/(ft.s) The terms absolute viscosity and kinematic viscosity are synonymous with viscosity. Kinematic viscosity is the ratio of viscosity to density.The SI unit is m^2 per sec. The cgs stoke is 1 cm^2 per sec.

Answer 4

the viscosity of a liquid is dependent on what the liquid is made of, and the bonding herein. Come on. if you need a grad school level answer you should be able to answer this yourself. My first year chem students can answer this without going into the bonding forces too deep.
