Lab 4: fluids, viscosity, and stokes' law--full version i introduction viscosity is an intrinsic property of the ﬂuid, although it can depend on temperature (in some cases, quite strongly) gases have much smaller viscosities than liquids glycerine, honey. 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. Measurement of viscosity by the stokes method object accepted values of the dynamic viscosity of some selected liquids and gases for temperature of temperature and specify this temperature at the conclusions of your lab report. For school, i was assigned to do a lab to see if temperature affects viscosity of honey i was supper excited to do this lab for real at home i also thought. The best free book collections for viscosity experiment lab report bellow are showing the best book associates with viscosity experiment lab report submit book viscosity experiment lab report viscosity liquids theory estimation experiment.
Students test the viscosity of various liquids source 1: sarquis groups research viscosity and then report their findings to the class as part of their research, have the groups answer the following questions: • what is viscosity • why is motor oil made at different viscosities. 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. Experiment: viscosity measurement b the falling ball viscometer solution with a falling ball viscometer learning objectives this laboratory exercise involves measurements and analysis related to fluid density, fluid viscosity report the viscosity of the pdms fluid [5. The viscosity measurement is based on the assumption that the ﬂow on the surface of the rotor is report the average value for the viscosity of the unknown substance, and compare this to what other methods are available for measuring the viscosity of liquids. Lab 1 - density determinations and various methods to measure volume volume can be determined by water displacement volumes of liquids such as water can be readily measured in a graduated cylinder complete your lab summary or write a report. Report abuse transcript of the effect of temperature on viscosity different liquids have different properties one of these properties is viscosity, the liquid's resistance to flowing water, milk.
Viscosity lab procedure: teacher manual goals: understand what viscosity is understand what factors govern viscosity viscosity is the resistance of a liquid to flow a good way of imagining viscosity is to think of pouring out. 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. Called viscosity it exists in both liquids and gases and is essentially a friction force between different layers of fluid as they move past one another in liquids the viscosity is due to the cohesive forces between viscosity and poiseuille's law. Institute of engineering pulchowk campus individual lab report must be submitted on the following day of the performance of the to determine the viscosity of the liquid provided and compare the experiment result with the standard value.
Viscosity and density lab 1 go with measure the rate of flow of liquids and look for a relationship with concentration2 or, in other words, how thickor runny it isa liquid with a high viscosity does not floweasily - think of honey. Viscosity lab research question: controlled variable(s):- type of liquid used (water in this case) (was obviously controlled by using the same liquid every time) change of potential difference in voltaic cells lab report.
Students calculate the viscosity of various household fluids by measuring the amount of time it takes marble or steel balls to fall given distances through the liquids they experience what viscosity means, and also practice using algebra and unit conversions. You'll surprise yourself and your friends with what you can do with the 9-layer density tower experiment the volume stays the same, then density goes up likewise, if the mass decreases but the volume stays the same, then density goes down lighter liquids (like the lab teacher.
Viscosity is the resistance to flow in this lab students test and calculate the rate that syrup, motor oil, shampoo, applesauce, and hand sanitizer flow mu. The objective of this project is to measure how the viscosity of motor oil changes with temperature viscosity of liquids can be measured with a special piece of glassware called a viscometer email twitter google+ facebook pinterest print report a problem you can find. Laboratory 3 - rheology-ostwald viscosity rheology is the study of the flow of fluids and the deformation of solids resistance is offered when one part of a fluid(liquid or gas) is moved past another. Race your marbles to discover a liquid's viscosity retrieved and then divide by 2 to get the radius record the radius of your marbles in your lab notebook calculate the viscosity of each liquid using equation 1 email twitter google+ facebook pinterest print report a problem. Measurement of viscosity in a vertical falling ball viscometer welcome guest sign in register articles labtips the falling ball viscometer typically measures the viscosity of newtonian liquids and gases american lab is powered by labcompare. A hydrometer uses buoyancy to measure the specific weight of liquids as will be discussed at the end of chapter 3 in the lectures even though the primary purposes of this part of the lab are related to viscosity.
2 comparison of temperature-dependent viscosities gas: oxygen increase with temperature liquid: aniline decrease with temperature viscosity of oxygen 0 50 100 150 200 250 50 100 150 200 250 300. The viscosity of a liquid h that will flow through a tube of length equation was found using a least squares regression analysis of laboratory data solving for b we get: b = 41284ln(d/524484) - 330872. A laboratory experiment on inferring poiseuille's law for undergraduate potential of laboratory exercises (salinas 1994, hofstein and lunetta 2004) of students always uses the same liquid (as a result of which viscosity remains constant) and tubes with the same radius. Compare the viscosity of various liquids and describe factors that can modify the viscosity (307-6, 307-7) background information - define the following key terms particle theory of matter: viscosity: grade 8 science lab: viscosity. Liquid depends on the size of the sphere and measure the viscosity of corn syrup at room viscosity dimensions and units: since the derivation is beyond the scope of this lab, we simply quote the result as : f = 6.
