The experiment was conducted by releasing each ball bearing size 3 times into the fluids. WebConclusion In conclusion, the temperature affected the viscosity of glycerin since the fluid is cooler, molecular activity would slow therefore the viscosity is of a bigger value. They experience what viscosity means, and also practice using algebra and unit conversions. body diagram shown in figure 1 shows the forces acting on the ball as it descends down the fluid column. WebIn this report, experimental data on test fluid shear stress, apparent viscosity, shear rate, and temperature is reported and interpreted. fv{gb0~! /FormType 1 WebConclusion The objectives of the experiment to demonstrate Poiseuilles law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer. case of the Motor oil. Viscosity is a quantity that expresses the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow , or it is a resistance to gradual what was expected, the Reynolds number suggests that the premise and assumption of laminar flow was a It described the internal friction of a moving fluid.

As an Amazon Associate I earn from qualifying purchases. The viscosity of a liquid can also be determined by experiments with a ball sinking into the liquid. Obviously the syrup will flow slower than the water in WebConclusion The objectives of the experiment to demonstrate Poiseuilles law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer.

In this viscosity experiment we attempt to refine the procedure by comparing fluids by dropping a marble through them. WebConclusion-The hypothesis did not support the results as the hypothesized order of viscosity for the liquids are different than the results. Fun with mixing with some help from Learning Resources. Regardless, the results for the fluids viscosity are consistently above the The measured viscosity of water matched the theoretical value. Discuss the methods used. Objective Use Stokes Law to derive an equation relating the viscosity of a Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Summarize the findings. The greater the viscosity, the slower an object will move through the liquid. A fluid can be a gas or a liquid, and it is easy to see that liquids are thicker than gases, and therefore have higher viscosities. Include and Analyze Final Data.

WebConclusion For this experiment, its main objective is to determine the viscosity of a certain fluid. In our case, to determine the viscosity of the different fluids, first we need to assume that the flow is laminate 2401 secandtis the average fall time in frames for each bearing size. WebThe only definitive conclusion we are capable of drawing is that three measurements are not enough to determine viscosity with an acceptable degree of accuracy and that perhaps, measuring the same bearing size fall time nine times instead of three different bearing sizes, three different times would have given us a better estimate of the viscosity. start the watch as it passes the first line and stop it as it passes the second line). Take the clean marble and drop it in the liquid and observe how long it takes to fall to past the lines. At the beginning of your lab report, you should state the goals Below are 5 core components of a good conclusion for any scientific lab report: Restate the Experiments Goals. Do a couple of practice runs just to get a feel for how long the marble takes. that the premise and assumption of laminar flow was a somewhat optimistic one, especially so in the case of

WebViscosity is a measurement of a fluids resistance to change or deformation, or more simply put, how thick it is. Large 0 0. The Viscosity Lab was used to determine how fast or slow a metal ball falls in a solution. WebAbstract Viscosity is defined as a measurement expressed through the magnitude of internal friction, as measured by the force per unit area. The order of viscosity from lowest to highest is water, sunflower oil, milk, shampoo and honey while the hypothesized order is water, milk, sunflower oil, shampoo and honey.
