If you use the same visometer to make the measurements than the terms h & g and volume are constant and you can establish that the ratio of the viscosity of one liquid to the viscosity of the second is equal to the ratio of the time it take to pass through the viscometer times the density of the liquid for the two liquids. Viscosity lab report by admin in essay samples on september 24, 2017 by referring to various web sites, it was found that the viscosity for castro oil and glycerol at room temperature were 0 65 and 1 0 nsa/ama respectively. [lab report operation unit] experiment 1(b) measuring specific gravity of a liquid by using hydrometer method a-level physics coursework - measuring viscosity experiment no 4 (viscosity)docx. The viscosity of a liquid is another term for the thickness of a liquid thick treacle-like liquids are viscous runny liquids like water are less viscous gases exhibit viscosity in the same way.
[lab report operation unit] experiment 1(a) measuring specific gravity of a liquid by using measuring beaker, eureka can, density bottle and hydrometer method viscosity comparison viscosity lab. (3) viscosity is an intrinsic property of the ﬂuid, although it can depend on temperature (in some cases, quite strongly) gases gases have much smaller viscosities than liquids. Viscosity 3 laminar shear, the non-constant gradient, is a result of the geometry the fluid is flowing through (eg a pipe), where μ is the proportionality factor called viscosity. Viscosity of liquids lap report 1815 words | 8 pages experiment 1: viscosity of liquids victoria kulczak lab partners: laina maines & heidi osterman date of lab: 2/21/11 due date: 2/28/11 abstract: the goal of this experiment was to determine the viscosity of given liquids.
According to the definition of viscosity mobile liquids have a relatively low viscosity fluidity is the reciprocal of viscosity , given as equation 1: f=1/ η fluidity is advantageous because solutions of mixed solutions of nonassociating liquids are roughly additive. Viscosity is the property of a fluid by virtue of which an internal resistance comes into play when the liquid is in motion, and opposes the relative motion between its different layers thus, it is the resistance of a fluid to flow. Experiments on the viscosity and freezing point of a starch water mixture form more useful, slow-moving liquids in order to use them effectively,.
Analysis of experimental uncertainties: density measurement physics lab ii objective this laboratory exercise allows students to estimate and analyze experimental uncer. Viscosity is defined as the resistance to flow ofa liquid or gas or, in other words, how thickor runny it isa liquid with a high viscosity does not floweasily - think of honey 5. Lab 6: fluids and drag iintroduction alearning objectives for this lab: 1learn how ﬂuids such as blood exert a pressure that varies with height 2understand the motion of objects in ﬂuids and how it depends on viscosity and density. Best answer: viscosity is a principal parameter when any flow measurements of fluids, such as liquids, semi-solids, gases and even solids are made viscosity measurements are made in conjunction with product quality and efficiency. The task for our lab was to determine the density of water and compare our recordings to the actual density of water listed in our lab packet then we were to find the density of an unknown liquid and find out what the substance was by matching its density with densities of substances listed in our packet.
The lower the viscosity of a liquid, the thinner the liquid is and the less resistance it experiences there are several methods that can be applied to measure the viscosity of a liquid, two of which are practiced in this experiment. Viscosity, the second group of students measures liquids with different viscosities, the rest of the variables remaining constant for example, six solutions of glycerol in water can be. The viscosity of water changes rapidly with temperature (see tables in the references) measure the temperature of the water at the beginning and end of the lab period.
Liquids can be described by their properties of color, texture and viscosity color - liquids can be any color or colorless texture - liquids can feel sticky, gooey, slippery, or watery to the touch. (1)viscosity is the tendency of the fluid to resist motion essentially it is a measure of the frictional force between adjacent layers of fluid as they slide past each other. Viscosity is a measure of the resistance of a fluid which is being deformed by shear stress or extensial stress what it means is its the resistance of a liquid to flow or its thickness viscosity describes a fluids internal resistance to flow for example pushing a spoon with a small force moves it easily through a bowl of water, but the.
The viscosity of a fluid is the measure of its resistance to gradual deformation by shear stress or tensile stress for liquids, it corresponds to the informal concept of thickness: for example, honey has a higher viscosity than water. Introduction: viscosity is a property of liquids that measures a fluid's resistance to flow the lower the viscosity of a liquid, the thinner the liquid is and the less resistance it experiences there are several methods that can be applied to measure the viscosity of a liquid, two of which are practiced in this experiment.
Volume by pycnometry pycnometry is a technique that uses the density relationship between volume and mass, and the vessel used is called a pycnometer to perform pycnometry measurements, the mass of the cylinder and the mass of a flask filled with water to a mark (a, fig 3) are recorded. Part i - viscosity key concepts: • viscosity tells us the resistance of a fluid on which a force is acting • for fluids, it basically refers to how 'thick' a fluid is. The viscosity measurement is based on the assumption that the ﬂow on the surface of the rotor is laminar after placing a new sample of liquid in the test cup, and raising the cup into position.
