Fluids and fluid flow liquids generally possess higher viscosities than gases air, of primary interest in aerodynamics, has a fluids and fluid flow http. The viscosity of liquids arises from an entirely different cause, namely, from the mutual attractions of the molecules, and is diminished by the effect of the wandering of the molecules consequently, the viscosity of gases increases while that of liquids diminishes as the temperature is raised. High interfacial viscosities significantly slow the liquid drainage rate and thus have a stabilizing effect on the emulsion emulsion interfacial viscosity plays a.

The accuracy of measurements of viscosity of liquids robert s marvin measurements to within 01 percent on ordinary liquids with viscosities below 1 p it is.
Viscosity is a measurable quantity that denotes a liquid's thickness a relatively thin liquid, such as water, has lower viscosity than a thicker liquid, such as honey or oil the measurement was discovered by french physicist jean léonard marie poiseuille. Method: the viscosities of liquids are determined by measuring the flow time for various liquids in an ostwald viscometer 2 ostwald viscometer 3 viscosity • the resistance of a liquid to flow is called its viscosity • viscosity is a property of liquids that is important in applications ranging from oil flow in engines to blood flow through. Some examples of highly viscous liquids are oils, honey, glycerin, tar and sulfuric acid viscosity is the ability of substances, especially fluids, to resist flow it can also be referred to as the measure of the ability of a liquid to resist being deformed by extensional stress the general. In industrial practice, viscosities of solutions (meaning homogeneous products of dissolution of solids or gases in liquids) and fluid mixtures (meaning homogeneous mixtures resulting out of mixing of two or more fluids) are often needed for the design of the different unit operations and processes.

In this investigation, you are going to make your own tool for measuring viscosity, called a viscometer, and use it to compare the viscosities of liquids you find around your home for instance, if your average flow rate for water was 20 seconds and corn oil took 600 seconds (5 minutes) to flow out. Michael smith engineers limited approximate viscosities of some common liquids liquid specific gravity at 16°c absolute viscosity cp temperature.

Viscosities: surface tension and liquid viscosity my report is dealing with liquid viscosity and how they are used to help us measure liquids and gives us the accurate temperature that we have today - viscosities: surface tension and liquid viscosity introduction. Properties of liquids: viscosity and surface tension viscosity the resistance of a liquid to flow is called its viscosity the greater the viscosity, the more slowly it flows. The viscosities of liquid sodium and potassium were estimated up to the critical temperatures according to the method recently described for mercury the critical absolute viscosity of sodium is 0072 centipoise and that of potassium 0055 centipoise, the estimated precision being plus or minus 001.
Fluid mechanics: fluid mechanics, science concerned with the response of fluids to forces exerted upon them it is a branch of classical physics with applications of great importance in hydraulic and aeronautical engineering, chemical engineering, meteorology, and zoology.
