Drop 1 214 0. Abstract: Experiment 1 looks at two fluid properties, density and viscosity. When the rate of shearing strain is directly proportional to the shearing stress, the constant of proportionality is called as absolute viscosity or dynamic viscosity. Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. us a better estimate of the viscosity. enough to determine viscosity with an acceptable degree of accuracy and that perhaps, measuring the same calculated can be found in the tables bellow. The experiment was conducted by releasing each ball bearing size 3 times into the fluids. 1. 311 Comments Please sign inor registerto post comments. Drop 2 218 0.

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. From the diagram, it can be clearly seen that the curve shifts in the direction of higher viscosity . Would a brookfield viscometer be useful as an analysis tool when the crosslinking occurs when the polymer no longer flows? HypothesisMy hypothesis is that when the temperature goes up, the viscosity goes down, and when the temperature goes down, the viscosity goes up. This gives the two variables an inverse relationship. After pouring the honey back into the graduated cylinder, we drop the metal piece into the cylinder, and time it. Discuss the methods used. We completed the Viscosity Experiment in class on March 18th. LAB REPORT SKILLS-CONCLUSION (Viscosity and Crosslinking of Polymers - Part B) - What conclusions can you draw regarding the viscosity and solubility of a polymer as a function of crosslinking? When you are writing the conclusion, it is important to revisit these goals and summarize how well they were met. The density distribution was analyzed for a mixture of high-melting explosive (HMX) and trinitrotoluene (TNT). Drop Frames 240 /s Velocity[m/s] Conclusion The objectives of the experiment to demonstrate Poiseuille's law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer. 2003-2023 Chegg Inc. All rights reserved. And I also guessed right because the cheerios were the cereal where the water passed faster. This is why it is perfectly acceptable to reject the hypothesis. 1.6 Conclusion It is clear that there is an ever increasing global burden of obesity, hypertension and cardiovascular disease, and diabetes with serious consequences and implications .
