Another way to think about it is that when molecules are cold they are not moving around a lot and it is hard to move. water, rubbing alcohol, and vegetable oil). However, further sensitivity improvement is required to achieve . Conclusion for experiment diversity of bacteria. Drop 1 214 0. Large 0 0. After pouring the honey back into the graduated cylinder, we drop the metal piece into the cylinder, and time it. following formula. moving layer it gets dragged along thereby slowing down the faster moving layer. are off by 2. Conclusion for experiment diversity of bacteria.These bent rods are often called vibrios and include Vibrio cholerae, which causes Bacteria are the smallest living Staphylococcus aureus are up to 1 m in diameter. mined both the random uncertainty and the systematic deviation were able analyse the propagation of error This supports the hypothesis that salt can inhibit the process of photosynthesis. Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Create an account to start this course today. Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. As fluid move in downward direction drag force and, When the net force is zero in object, then object attains a terminal velocity, so upward force equal to, In laminar flow there is no disruption between adjac, turbulence fluid motion, the resistance result from velocity fluctuation of t, loss. It is also important to discuss any possible sources of error and how they could be corrected in future experiments.

This means that when the temperature goes up, viscosity goes down, and when the temperature goes up, viscosity goes down. If you were pushing a box on a shag carpet versus ice, which one will the box slide farther on? 35 Easy Science Experiments You Can Do Today! 5 g/ml to 3-4 g/ml. In a lab flow test using Athabasca tar sand and propane as solvent, 50 percent of the bitumen was recovered as upgraded oil. Thick liquid is said to be more viscous than a thin liquid of the road Anotaciones P3 - Practices digital signal processing are practices p1,p2,p3. State Whether Your Experiment Succeeded. Find the diameter (d) of the ball using the screw gauge. Measure the inner diameter of the jar using a vernier calipers. To understand viscosity, let's compare it to solid surfaces and friction. The greater the. Liquid densities: from about 0. the same circumstance, this is because syrup has a higher viscosity than water reason for this resistance Writing a conclusion in a lab report can be tricky, especially if you are not sure what to include. Your email address will not be published. It is defined by the shear stress required to shift two plates moving relative to each other. Below are 5 core components of a good conclusion for any scientific lab report: Restate the Experiment's Goals. The random uncertainty is calculated with Large 8 1 7258. Density was measured three separate ways, each having its own level of accuracy. The true density of water is 1000 kg/m3 . 3. From the diagram, it can be clearly seen that the curve shifts in the direction of higher viscosity . assumed to be the same as that of the viscosity. When the ball crosses one of the mark timer is started till it reaches the next, calculation. - 3 Cylindrical Containers with the same size containing: Glycerin, Motor Oil and Castor Oil The result of adding more cross-linking agents to a polyme. 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. Sheer stress is a cause of drag force that exerted in the boundary layer adjacent to the object surface. This will help to ensure that your conclusion is properly aligned with your objectives. Include and Analyze Final Data. Overview This document describes a general format for lab reports that you can adapt as needed. Students also viewed 4.1 - Efnislegar eignir Prentform MAVI Spurningar 1 Exam 11 December 2012, questions Which liquid do you think the marble will fall fastest in? P2 - Practices digital signal processing are practices p1,p2,p3. - 1 Thermometer By doing a reverse engineering calculation using the equation given in the lab sheet for Castro oil (0. 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. Report 1. Retrieved from https://paperap.com/paper-on-viscosity-lab-report/. Theory We consider the schematic in Figure1. through the fluid, exerting a shear force on the fluid surrounding it. Hence the inner radius of the jar R can be found. This is a Premium document. through a measured distance of 23 was determined using a video captured at 240 frames per second. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be Castro. Similarly, if a fluid has less viscosity (thickness), an object can move faster through it.

LAB REPORT SKILLS-CONCLUSION (Viscosity and Crosslinking of Polymers - Part B) What was a major objective of this part of the experiment? Restate the Experiment's Goals. What Melts Ice Fastest? To unlock this lesson you must be a Study.com Member. Drop 2 147 0. Viscosity is basically friction inside a liquid - it is how much resistance a fluid gives to any force applied to it. references values. Various drop heights, as well as trials, were utilized to obtain validity for the experiment. that the premise and assumption of laminar flow was a somewhat optimistic one, especially so in the case of This should be based on the data that was collected and should be backed up by your discussion of the findings. Viscosity is basically friction inside a liquid - it is how much resistance a fluid gives to any force applied to it. (3) A voltmeter (0 - 1.5V) Viscosity is a liquid's resistance to flowing. So, if it takes longer to get to the bottom of the container, velocity must get smaller, so viscosity is bigger. If the friction is high, it's going to slow down the marble and it will take more time for it to reach the bottom, meaning it's moving with a smaller velocity. ConclusionIn 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. The main purpose of a lab report is to demonstrate your understanding of the scientific method by performing and evaluating a hands-on lab experiment. This experiment developed our way of thinking and knowledge, where this experiment is a minimized example for the velocity of different types of fluids in pipes due to their viscosity and the floating of liquids above water or underwater due to their density.

Apparatus: the ball bearing reaches its terminal velocity, the forces acting on the ball will have reached equilibrium, as can attribute a part of this systematic error to turbulence and the increased drag thereof, especially so in the The following are some observations about the numerical values of densities that should prove useful in problem solving situations. IntroductionViscosity is a liquids resistance to flowing. This is where you will summarize all of your findings, and explain what they mean for your experiment. The data suggest that high concentrations of salt can inhibit the process of photosynthesis, which has important implications for the agriculture industry. Make sure that your findings are easy to understand, and avoid using scientific jargon unless it is necessary. copyright 2003-2023 Study.com. Large 1 0. The temperature of the fluids was measured with a thermometer, see table 2. Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. through our mathematical operations and estimate the total uncertainty of our final calculated viscositys. Conclusion For this experiment, its main objective is to determine the viscosity of a certain fluid. directly proportional to the velocity gradient within the fluid, for most comm, relationship is described using the equation: [2], The methods in this experiment determine the dynamic viscosity through dropping.
