## Essay on Viscosity Lab Report

Ã˜ You must select one of solutions 2-6 and show me each calculation across the spreadsheet. Of course, some liquids are more viscous than others. In this activity, we will measure the viscosities of a few household fluids by dropping balls into them and measuring the terminal velocities. Fluid mechanics includes hydrodynamics, the study of force on liquids, and aerodynamics, the study of bodies moving through air. Cohesive and adhesive forces are important for the transport of water from the roots to the leaves in plants.

This evaporation can occur in a river or in a soil within plant. We will get a highest rate of the transpiration when we combined the wind and the light. Methylcellulose is available in several types designated according to the viscosity of a 2 % aqueous solution. The same rate of flow procedure performed on the water was performed on the methanol solutions. Once all the needed chemicals were added we waited for about 70-75mintues for the reaction to take place.

The experiment is a simple way to explain and measure the viscosity of a liquid. The temperature as well as the height of the glycerol was measured. We were asked to measure the benzoic acid concentrations of the feed, raffinate, and extract streams. This objective was carried out by filling a glass bulb to a pressure of about 700 Torr with the desired gas and letting it evacuateâ€¦ 721 Words 3 Pages Viscosity Science Lab Purpose: To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid. High viscosity fluids like honey and glue resist the changes caused by these forces the best. According to the definition of viscosity mobile liquids have a relatively low viscosity.

Record the time in your data table. Which liquid do you think the marble will fall fastest in? Open the stopcock all the way and start the timer as the meniscus hits 0mL. Grade 8 Do you agree with this alignment? Methemoglobin is not a problem in adults since they have an enzyme that converts methemoglobin back to hemoglobin. We will use an Ostwald viscometer. However, the nature of non-Newtonian mixtures will be discussed in lecture. 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.

How can you tell which liquids are thicker and which are thinner using the velocity? Conclusion- The hypothesis did not support the results as the hypothesized order of viscosity for the liquids are different than the results. You will notice that it takes longer to pour out the Corn Syrup and Honey than it does to pour out the Water and Cooking Oil. One example of a high-viscosity fluid is honey. Can anyone name an example of a low-viscosity fluid? There are two main reasons for doing this: 1 Ease of communication: it is easier to find what you want from a study if it is written in the standard format. Friction between the molecules of a fluid resists fluid change and deformation. Two students should work on section A and B, and two students should work on section C.

Yes No Thanks for your feedback! Leaf transpiration occurs through stomata. The second method involves dropping a foreign object, in this case a sphere, into a cylinder of glycerol and measuring the time it takes for it to travel a specific distance down the tube. I hope you enjoyed the experiment. The answer is a property of liquids called viscosity. These are all fundamental and intrinsic property of a liquid. Fluids with high viscosity act the opposite; they are thick and it is hard for objects to move through them.

## Viscosity of a Liquid Experiment

Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. Part C - Prepare solutions of methycellulose 400 in the concentrations of 1, 0. The viscosity of a 0%, 20%, 40%, 60%, 80% and 100% methanol by volume solutions was measured to be 0. Learning to write laboratory reports will provide you with a valuable and transferable skill. Note: your viscosity lab might have produced some variance in this order depending on what type of each product you use. Rotational viscometer provide ability to measure not only the viscosity of a fluid, but also shear rate and shear stress, torque, temperature and frequency of.

This property of the fluid can be used to determine the rate of mass transport, diffusion or within that liquid when it is to be used as a solvent. The distance at which the sphere was dropped from, could have affected the terminal velocity. All fluids, from liquids to gases illustrate the property of viscosity to some degree. The viscosity of a 0%, 20%, 40%, 60%, 80% and 100% methanol by volume solutions was measured to be 0. The density of acetone is 0. Viscosity can be thought of as fluid friction, just as friction between two solids resist the motion of one over the other, also possible to cause an acceleration of one fluid relative to the other.
