Lab results and process calculations show that low-pressure, low-energy solvent-based in situ processes have considerable technical and economic potential for upgrading and recovery of bitumen and heavy oil. 10. Drop 3 146 0. it is not safe to arrive at conclusions due to the high reactivity of the compounds at the concentrations used in the . When heat is applied to fluids, molecules can then slide over each other more easily making the liquid becomes less viscous. By referring to various web sites, it was found that the viscosity for Castro oil and glycerol at room temperature were 0. Cross-Linking Poly (vinyl alcohol) with Sodium Borate Objective:The objective of this experiment is to explore the change in physical properties of a polymer as a result of cross-linking. The true density of water is 1000 kg/m3 . 999 kg/m 3 , we find that we this is to look at the flow of water versus the flow of syrup. Drop 1 52 1. Drop 3 42 1. 2003-2023 Chegg Inc.

This experiment was successful in answering the research question posed at the beginning of the lab report. EXPERIMENT TO DETERMINE THE VISCOSITY OF GLYCERINE. AMAZING RACE: MEASURING THE VISCOSITY OF SOME LIQUIDS LABORATORY REPORT EVALUATION FORM GENERAL CHEMISTRY 2 LAB ACTIVITY 6 LAB REPORT RUBRIC. How Does the Consistency of a Liquid Impact Magnetic Attraction, Color Changing Walking Water Science Experiment. Viscosity is a measure of the resistance of a fluid which is being deformed by ei- ther shear stress or tensile stress. Drop Frames 240 /s Velocity[m/s] buoyancy is given by the following equation, Wherefluidis the density of the fluid,Vis the volume of the sphere andgis the gravitational acceleration. Content uploaded by Bilal Ahmad. Low viscosity fluids flow easily (water, alcohol); High viscosity fluids pour slowly (molasses, cold honey, etc.). Find the diameter (d) of the ball using the screw gauge. enough to determine viscosity with an acceptable degree of accuracy and that perhaps, measuring the same Viscosity occurs due to friction between adjacent layers of the fluid that are moving different velocity. The density of the ball bearings were calculated with the following formulas Sphere Average Speed[m/s] Standard deviation Method1. This supports the hypothesis that salt can inhibit the process of photosynthesis. Finally, the conclusion should offer some suggestions for further research. A lab report conveys the aim, methods, results, and conclusions of a scientific experiment. Medium Re Comments/ extra information on viscosity experiment: Strain is the geometrical measure of deformation representing the relative displacement between particles in the material body, i.e. According to equation 2, the weight of a sphere (W, Law of Contract & Problem Solv (LAW-22370), Biochemistry and Molecular Biology (BIOC0001), Business Data Analysis (BSS002-6/Ltn/SEM1), Foundations of Occupational Therapy (160OT), Introduction to English Language (EN1023), 3. You can also try other liquids. Since velocity is equal to distance divided by time, velocity is inversely proportional to time as well. Although the viscosity was within an "acceptable" range of what was expected, the Reynold numbers suggest forces acting on the ball bearing and calculate the viscositys of the fluids by applying Stokes law. All the record results were fine but with some error percentage suitable to some different factors, one way is to rope the spheres just above the surface to reduce the increase in velocity, also the errors can be minimized by recording the timings precisely and increasing the number of repetition of the time recording to get an accurate average. Remember to use clear and concise language, and to avoid getting bogged down in the details. The experiment shows that the slower the time, the higher the viscosity is for a liquid and the faster the time, the lower the viscosity is for a liquid. Stress is a measure of the average amount of force exerted per unit . Drop 2 135 0. Glycerin 3. Writing a conclusion in a lab report can be tricky, especially if you are not sure what to include.
