Viscosity lab report
Wet pvt lab pete 310 lab # 6 determination of viscosity for oil samples learning objectives gain a basic knowledge of the techniques used to measure viscosity learn to use a rotational and a glass capillary viscometer viscosity is the measure of the internal friction of fluid. Viscosity is the property of a fluid that tends to prevent it from flowing when subjected to an applied force high-viscosity fluids resist flow and low-viscosity fluids flow easily. Viscosity is an internal property of a fluid that offers resistance to flow it is due to the internal friction of molecules and mainly depends on the nature & temperature of the liquid many methods are available for measuring viscosity of polymer solution.
Unit 12 viscosity of solutions 112 mud, paints, and inks the opposite, solutions that become less viscous when the shear ends are called “rheopectic. Viscosity measurement purpose note that most samples have been sitting overnight in the lab unless the ﬂuid temperature has been disturbed, eg, by execessive handling, it should be in report the average value for the viscosity of the unknown substance, and compare this to. Engine oils and lubricants need to provide a good layer thickness by having sufficient viscosity, without giving significant frictional effects from the viscosity being too high the ideal viscosity range of an engine oil is therefore quite narrow.
Brookfield viscometry is a test of dynamic viscosity which involves a spinning shaft in contact with the fluid to be measured this type of viscosity testing is often used to analyze fluids according to dynamic viscosity specifications which are measured in centipoise our clients often request this. Experiment v | viscosity of oil by the rotating cylinder method brendan arnold 27th april 2003 abstract check the equipment between laboratory sessions after much investigation, it is apparent that after the rst two sets of data the results were taken over twelve rotations for the analysis we have assumed that this was the case. View lab report - viscosity lab report from ce 320a at new jersey institute of technology experiment #1 viscosity of liquids ce 320 a group # 1 submitted by: nicole gonzalez-sitja introduction the.
12) viscosity (viscosity will be discussed in a later lab this semester) the dynamic viscosity (m) for a fluid [ft/l 2] is the ratio of the shear stress (t) acting on a fluid to the resulting rate of angular strain, which is the velocity (v or u) gradient (dv/dy or du/dy) where y is the coordinate distance normal to the direction of flow for. Viscosity measurement objectives for the student: a rotating spindle-type viscometer 2 investigate 10w-30 oil is a newtonian or non-newtonian fluid 3 determine the viscosity of 10w-30 motor oil as a function of temperature attach it to your lab report 1 turn on the viscometer head and allow it to warm up for 10 minutes. The laboratory reports on oil samples typically contain a great deal of test data along with comments and recommendations although the statements should be clear and comprehensible, they may not tell the complete story. 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 materials: • 3 different colored blocks of clay.

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 in this experiment, the viscosity of various liquids are compared. (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 (2) definition: consider two parallel plates of area a, separated by a fluid layer of thickness d. A laboratory experiment on inferring poiseuille’s law for undergraduate tube, respectively, η is the viscosity of the ﬂuid and p is the pressure difference between the potential of laboratory exercises (salinas 1994, hofstein and lunetta 2004), which allow.
4me-a group no 8 experiment no 8 measuring of viscosity by saybolt viscometer date performed: feb 3, 2016 date submitted: feb 9, 2016 leader: curio, lance victor s. Big idea 1: generally, the more dense a fluid is, the higher its viscosityfor example, corn syrup was the most dense fluid in our lab and it also had the highest viscosity however, this is not always the case because oil is slightly less dense than water, but oil still has a higher viscosity than water.
Emulsion polymerization and characterization of ethyl acrylate and styrene 2/8/1999 introduction emulsion polymerization of monomers capable of stabilizing a free radical (eg styrene) and monomers using redox initiators (eg acrylates) has been found to yield higher mw polymers due to the lack of termination occurring in the micelles. Measure fluid viscosity pre-laboratory assignment review the sds on sucrose and acetone look up the literature values of density and 3 using all the class data, report the viscosity as a function of concentation and temperature along with its 95% ci 4 compare your values of density and viscosity with values from the. Viscosity of a liquid experiment for this experiment, we are going to test how marbles behave differently based on the type of liquid they are dropped into the experiment is a simple way to explain and measure the viscosity of a liquid. Abstract this report is intended to explain an experiment performed to determine the viscosity of butcher oil as a function of temperature and to determine weather the oil was a newtonian or non-newtonian fluid.
