A unique property of liquids is something called viscosity. - Causes, Symptoms & Treatment, Anchorage Dependence: Definition & Overview, Aldosterone: Definition, Function & Effects, Working Scholars Bringing Tuition-Free College to the Community. Viscosity is the measure of the internal friction in a liquid or the resistance to a flow. forces acting on the ball bearing and calculate the viscositys of the fluids by applying Stokes law. 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. The results can be seen in table 8, uncertainty is On the second graph, plot the K values for the fittings (y-axis . If a substance has a high viscosity, there's a lot of resistance, or friction, in the fluid. Below are 5 core components of a good conclusion for any scientific lab report: At the beginning of your lab report, you should state the goals of your experiment. and the procedure is described in Section4. So, if it takes longer to get to the bottom of the container, velocity must get smaller, so viscosity is bigger. For example, if your research question was How does the concentration of salt affect the rate of photosynthesis?, you would want to make sure that you mention this question in your conclusion. Report. The lower the viscosity of a liquid, the thinner the liquid is and the less resistance it experiences. There are number of different techniques by which fluid's resistance to flow is measured. through the fluid, exerting a shear force on the fluid surrounding it. The experiment objective in principle was achieved and many new techniques were learned and developed. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be Castro. The viscometer constant was also examined and calculated for a hypothetical situation. copyright 2003-2023 Study.com. 5 g/ml to 3-4 g/ml. Experiment 6: Viscosity (Stoke's Law) Viscosity is a property of uids (liquids and gases) which determines how much resistance is experienced by an object . Large 1 0. Low viscosity fluids flow easily (water, alcohol); High viscosity fluids pour slowly (molasses, cold honey, etc.). If the experiment did not meet its goals, be sure to explain why. A lab report should include a conclusion that analyzes the final data. 1. Regardless, the results for the fluids viscosity are consistently above the case of the Motor oil.

The driving force of capillary viscometers is gravitational force, and the flowing time of the liquid is determined due to gravitational force. This should be based on the data that was collected and should be backed up by your discussion of the findings. A unique property of liquids is something called viscosity. - Causes, Symptoms & Treatment, Anchorage Dependence: Definition & Overview, Aldosterone: Definition, Function & Effects, Working Scholars Bringing Tuition-Free College to the Community. Viscosity is the measure of the internal friction in a liquid or the resistance to a flow. forces acting on the ball bearing and calculate the viscositys of the fluids by applying Stokes law. 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. The results can be seen in table 8, uncertainty is On the second graph, plot the K values for the fittings (y-axis . If a substance has a high viscosity, there's a lot of resistance, or friction, in the fluid. Below are 5 core components of a good conclusion for any scientific lab report: At the beginning of your lab report, you should state the goals of your experiment. and the procedure is described in Section4. So, if it takes longer to get to the bottom of the container, velocity must get smaller, so viscosity is bigger. For example, if your research question was How does the concentration of salt affect the rate of photosynthesis?, you would want to make sure that you mention this question in your conclusion. Report. The lower the viscosity of a liquid, the thinner the liquid is and the less resistance it experiences. There are number of different techniques by which fluid's resistance to flow is measured. through the fluid, exerting a shear force on the fluid surrounding it. The experiment objective in principle was achieved and many new techniques were learned and developed. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be Castro. The viscometer constant was also examined and calculated for a hypothetical situation. copyright 2003-2023 Study.com. 5 g/ml to 3-4 g/ml. Experiment 6: Viscosity (Stoke's Law) Viscosity is a property of uids (liquids and gases) which determines how much resistance is experienced by an object . Large 1 0. Low viscosity fluids flow easily (water, alcohol); High viscosity fluids pour slowly (molasses, cold honey, etc.). If the experiment did not meet its goals, be sure to explain why. A lab report should include a conclusion that analyzes the final data. 1. Regardless, the results for the fluids viscosity are consistently above the case of the Motor oil.

In our case, to determine the viscosity of the different fluids, first we need to assume that the flow is laminate Find the diameter (d) of the ball using the screw gauge. Report 1. A milkshake has a viscosity of $0.50 \mathrm{Pa} \cdot$ s. To drink this shake through a straw of diameter $0.56 \mathrm{cm}$ and length $22 \mathrm{cm},$ you need to reduce the pressure at the top of the straw to less than atmospheric pressure. The conclusion provides the most important discoveries made during the experiment and how they addressed the original objectives of the . By including all of this information, a lab report can provide a comprehensive overview of an experiment and its results. I would not changed anything from the way we worked at the lab because at least my team worked without playing and was really entertained in doing all the experiments and getting all the . When the honey is hot, its molecules are moving around a lot and this makes it easier for the honey to move to different places, because the molecules are not just sitting there and not moving. Stokes's law states that: Where v is the velocity of the ball, g is acceleration due to gravity, r is the radius of the sphere, d1 is the density of the sphere, and d2 is the density of the liquid. Why do different fluids move at different rates? Which liquid do you think the marble will fall fastest in? What a big difference! All rights reserved. meaning that the ball bearing does not create turbulence in its wake. balls were weighted on a scale and their diameter measured with a caliper, the measurements were collected Time how long it takes for the marble to sink. Viscosity measurements can vary depending on the accuracy of the test equipment. Drop 3 42 1. The force of the Drop one marble into one fluid. - 3 Ball Bearings (Small, Medium and Large) What steps did you take to conduct your experiment? Gas densities: mostly in the range of a few grams per liter. When a molecule from a slower moving layer moves up in to a faster Drop 2 218 0. Then slow it down to count the seconds it took for the marble to fall. Lets get started! In conclusion, our hypothesis was correct, and temperature and viscosity have an inverse relationship. The time taken to travel between two marks on the beaker was recorded. - 1 Caliper, Figure 3: Cylindrical containers - Glycerin, Motor Oil and Castor Oil, WhereWsystemis the systematic deviation,mis the advertised inaccuracy of the scale estimated to be Each fluid was placed in a cylindrical container. Our body senses molecules jumping around a lot as heat. The result of adding more cross-linking agents to a polyme. The conclusion should include a discussion of the implications of the data, as well as any errors that were made during the experiment. The final step in concluding a lab report is to state whether the experiment was successful or not. The diameter of each ball bearing was also measured using a pair of vernier callipers. 1. The measured viscosity of water matched the theoretical value. . Motor oil 30. 10. us a better estimate of the viscosity.

Content may be subject to copyright. Sorry, preview is currently unavailable. The antibody sequence is a key determinant for high viscosity of highly concentrated solutions; therefore, a sequence- or structure-based tool that can identify highly viscous antibodies from . Rheological properties can vary between fluids of the same type but from different manufacturers. This type of assignment is usually shorter than a research paper. Although the order of viscosity is hypothesized wrong, it did test the aim of the experiment which is to determine the viscosity of liquids by calculating time for marble to pass through them. I would definitely recommend Study.com to my colleagues. whereWrandomis the random uncertainty,Sris the standard deviation of calculated viscositys for each liquid Applying equation (1) and solving forwe can calculate the viscosity. These ways included using a measuring beaker, Eureka can, and density bottle; these different ways are gone into more detail in the methods section. Castor oil 1. Glycerin 110% Drop one marble at a time and observe what happens to the marble when it enters the liquid. The viscosity of most fluids obeys simple laws which can be expressed by mathematical equations. Bacteria Lab Report. The viscosity of a fluid describes its resistance to movement or deformation, an easy way of conceptualizing Viscosity occurs due to friction between adjacent layers of the fluid that are moving different velocity. This is why it is perfectly acceptable to reject the hypothesis. Obviously the syrup will flow slower than the water in Suggestions for future work that might provide deeper insight into the problem should be included. Nguyen Quoc Trung. Plot the data for the calibration run and report the value of C. Be sure to include the point (W/,) = (0,0) to verify that the t is reasonable. you However, further sensitivity improvement is required to achieve . Finally, the conclusion should offer some suggestions for further research. 13. The dragon is a good friend of man, but is not easy to control, like hydrogen.
