Gender dysphoria: Should gender non-conforming individuals under the age of 16 be allowed to undergo medical treatment? P2 - Practices digital signal processing are practices p1,p2,p3. Drop Frames 240 /s Velocity[m/s] Clean the glass jar and fill it with the viscous fluid. Holy moly! Place a meter scale vertically beside the jar. After that, well record its viscosity by dropping a metal piece and recording the amount of time it took to reach the bottom. Time how long it takes for the marble to sink. The ice has less friction, so the box will slide further. Log in out of 10 2. Report. 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. Students looking for free, top-notch essay and term paper samples on various topics. Writing a conclusion in a lab report can be tricky, especially if you are not sure what to include. In a lab flow test using Athabasca tar sand and propane as solvent, 50 percent of the bitumen was recovered as upgraded oil. (1) Two resistors of unknown resistances - 3 Cylindrical Containers with the same size containing: Glycerin, Motor Oil and Castor Oil shown in the equation below the frictional shear forces between them. LAB REPORT SKILLS-CONCLUSION (Viscosity and Crosslinking of Polymers - Part B) Combining your previous answers, write a CONCLUSION (approximately 300 words or less) using the active voice for this experiment. that the premise and assumption of laminar flow was a somewhat optimistic one, especially so in the case of Viscosity is basically friction inside a liquid - it is how much resistance a fluid gives to any force applied to it. 005 gandmis the weight of each individual bearing size. Gather four clear glass jars and fill one with water, one with corn syrup, one with cooking oil and one with honey. Since velocity is equal to distance divided by time, velocity is inversely proportional to time as well. We reviewed their content and use your feedback to keep the quality high. Widely, it is used for measuring the viscosity of Newtonian fluids. In everyday terms (and for fluids only), viscosity is "thickness". The measured viscosity of water matched the theoretical value. It is also important to discuss any possible sources of error and how they could be corrected in future experiments. Regardless, the results for the fluids viscosity are consistently above the This should be based on the data that was collected and should be backed up by your discussion of the findings. Filtration time was 1.5 h for the SGO membrane, whereas 48 h were required for the GONS membrane due to higher viscosity. 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. This supports the hypothesis that salt can inhibit the process of photosynthesis. LAB REPORT SKILLS-CONCLUSION (Viscosity and Crosslinking of Polymers - Part B) What is the real-world implications from this experiment? assumed to be the same as that of the viscosity. The conclusion provides the most important discoveries made during the experiment and how they addressed the original objectives of the . 3. The result of adding more cross-linking agents to a polyme. Accordingly, one possible justification for this problem could have been the liquid unknown type, which we assumed to be Castro. Thats nearly half an hour! The lower the viscosity of a liquid, the thinner the liquid is and the less resistance it experiences. For example, honey is more viscous than water. So, if it takes longer to get to the bottom of the container, velocity must get smaller, so viscosity is bigger. Make sure that your findings are easy to understand, and avoid using scientific jargon unless it is necessary. Which marbles sinkto the bottom of the jar quickly and which marbles sink to the bottle of the jar slowly. References The answer is a property of liquids called viscosity.

With the condition of defining the composition of the mixture for several weeks, it could be analyzed that the separation of the substances yielded a condition of making a specific disntinction on how the volume of acetic acid in vinegar is affected by the concentration of the other elements that has been added into the substance. Data measured and When one variable gets bigger, the other gets smaller. [1] Considering the fact that the Reynold numbers were consistently above one, perhaps we It took 5m, 36.51s (336.51 s) to fall to the bottom! Temperature in Farenheight Time in secsCold 28.20 2246.80Room Temp 72.70 336.51Hot 208.00 1.43. Its like a teacher waved a magic wand and did the work for me. Report. Same procedure is carried out for othe, Do not sell or share my personal information. The surface stress biosensor was developed as a new type of biosensor to detect protein molecule concentration and has a wide range of clinical applications. The force of the In conclusion, our hypothesis was correct, and temperature and viscosity have an inverse relationship. The greater the. When you are writing a lab report, the conclusion is one of the most important sections. How much did you enjoy doing the experiment? The conclusion should include a discussion of the implications of the data, as well as any errors that were made during the experiment. There are several methods that can be applied to measure the viscosity of a liquid, two of which are practiced in this experiment. As This lab report will address changes in rheological parameters of fluids measured (2019, Nov 27). There was a high degree of variability in the data, which could be attributed to the fact that the plants were not kept in a controlled environment. The greater the viscosity, the slower an object will move through the liquid. Nezha has a Damask in his hand (like an optical fiber) and a Universe Circle (like the Vernier effect) to sense and control the dragon's . 10.6 Viscosity Test of Bitumen 10.6.1 Introduction Viscosity is reverse of fluidity. 2. 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. Drop 1 43 1. The answer is a property of liquids called viscosity. This type of assignment is usually shorter than a research paper. (3) A voltmeter (0 - 1.5V) The diameter of each ball bearing was also measured using a pair of vernier callipers. Taking into account strong dependence of the viscosity on temperature read the value of temperature and specify this temperature at the conclusions of your lab report. Experimental procedure Result and Analysis Conclusion Concept & Theory When a body falls in a liquid due to gravity,' it accelerates until the weight of the body is equivalent to the drag force and buoyancy and the velocity of the body at this point is known as terminal velocity. The actual density of steel is equal to 7800 kg/m 3 , when compared to Discuss your results, focusing on the following: You're trying desperately to shake it, but to no avail. Honey sure has high viscosity! Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. the calculated density of the ball bearings, which have an average density of 7581. - 1 Scale (1 decimal) mined both the random uncertainty and the systematic deviation were able analyse the propagation of error the resistance to an externally applied shear stress. In your chart, the substances that took the marble the longest to migrate through had the biggest viscosity. 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. Given this we are able to determine the Numerical investigations were conducted on the mixing efficiency of resonant acoustic mixing (RAM) technology using a high-viscosity mixture under vertically forced vibrations. Cite this page Viscosity Research Paper Pages: 2 (520 words) . The density of the ball bearings were calculated with the following formulas Was your prediction correct? How did you know. Glycerin 110% Sorry, preview is currently unavailable. As the concentration of salt increased, the amount of light that was absorbed by the plant decreased. 5 g/ml to 3-4 g/ml. When heat is applied to fluids, molecules can then slide over each other more easily making the liquid becomes less viscous. Why do you think that? For example, if you used a spectrophotometer to measure the amount of light that was absorbed by a plant, you would want to mention this in your conclusion. This will help to ensure that readers understand how the data was collected and can evaluate its reliability. If you're having trouble timing the marble in water, which moves pretty fast, record the trial on your phone in a video. Table 8: Mean Reynold Numbers from final results. - 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 - Science Experiment, Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, Homemade Ice Cream in a Bag Science Experiment, High School Biology: Homework Help Resource, Environmental Science 101: Environment and Humanity, Prentice Hall Biology: Online Textbook Help, Middle School Physical Science: Help and Review, Middle School Physical Science: Tutoring Solution, Human Anatomy & Physiology: Help and Review, Distribution of Plants & Animals Around the World, Landforms, Climates & Ecosystems of the Earth: Patterns & Characteristics, What is Lichen Planus? (2) By Experiment Since we're just interested in how viscosity affects velocity of the sphere, let's look at how those two variables are related in the equation. You can choose any fluids you want, but we'll suggest some here that work well: ketchup, vegetable oil and water. A factor closely associated with renal disease status in clinical diagnosis is abnormal human serum albumin (HSA) concentration levels in human body fluids urine, serum, etc. Drop Frames 240 /s Velocity[m/s] Stress is a measure of the average amount of force exerted per unit . Viscosity is one of the properties to describe the " fluidity " of fluid. Conclusion: It is a measure of the resistance to flow. Report 1. It is a measure of a fluid's resistance to flow. What steps did you take to conduct your experiment? Drop 1 52 1. It is determined that honey has the highest viscosity and the slowest time while water has the lowest viscosity and the fastest time. copyright 2003-2023 Study.com. Restate the Experiment's Goals. what was expected, the Reynolds number suggests that the premise and assumption of laminar flow was a In conclusion, our hypothesis was correct, and temperature and viscosity have an inverse relationship. A lab report should include a conclusion that analyzes the final data. This is a Premium document. Use the template provided to prepare your lab report for this experiment. the same circumstance, this is because syrup has a higher viscosity than water reason for this resistance We completed the Viscosity Experiment in class on March 18th. 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 . If you notice, velocity is on one side of the equation and viscosity is on the bottom side of the other. Although the viscosity was within an "acceptable" range of what was expected, the Reynold numbers suggest This will help to ensure that your conclusion is properly aligned with your objectives. 1. But, when you spill your water, it goes everywhere. 3. Medium 7 1 7758. IntroductionViscosity is a liquids resistance to flowing. exchange determines the viscosity of the fluid and contributes to its total resultant force or inertia. Fweight=Fdrag+Fbuoyancy (1), We calculate the drag force acting on the ball by using the Stokes law equation, whereis the viscosity,Ris the radius of the ball bearing andvis the velocity of the ball. The results indicated that although the viscosity was within an acceptable range of Finished completely. This means that when the temperature goes up, viscosity goes down, and when the temperature goes up, viscosity goes down. Report, (4) A rheostat (10 ohm) Nguyen Quoc Trung.
