## Oil Viscosity

Also, at the conclusion of the experiment, be sure to dispose of the used motor oil properly. Looking for more science fun? The absolute minimum is twice a year. Its unique shape and curve makes it more outstanding compared to other pumps in delivering material with larger powders. The suction is then released, allowing the sample to flow back through the tube under gravity. Image courtesy of Marshall Space Center.

## The Viscosity of Motor Oil

Water is used as the basis for the viscosity index because we are all familiar with how fast it moves. They also may have more viscosity-index improvers in them. For each test, crew members will release a drop from a syringe onto separate strings and record digital video of the drops as they coalesce to form one drop. Which one will flow faster from the beaker if it is tipped on its side? Do not seal the bottle against the clay. The Viscosity of Motor Oil www. Grades 9 - 12 Do you agree with this alignment? The point at which the force exerted by gravity on a falling object is equaled by a fluid's resistance to that force.

## How To Pick The Right Motor Oil

What's really important is that you use the oil viscosity your car's owner's manual recommends. Because molasses is more resistant to flow, it has a higher viscosity than water. So the equation tells you to take the density of the sphere minus the density of the fluid Ī Ļ , multiply this by 2 ga 2, and then divide the result by 9 v. Each will be evaluated several times with different drop diameters for each sample. Which marbles sink to the bottom of the jar quickly and which marbles sink to the bottle of the jar slowly.

They apply basic calculus and the work-energy theorem for non-conservative forces to quantify the friction along a curve. Even if the numbers on the container don't indicate it, there's a fairly wide range for each viscosity rating and the higher-mileage oils sit at the top of each range. An example is butter, which is solid at room temperature. What factors do you think might cause you to get different times for the same liquid? Your third task is to pick the viscosity thickness that's suitable for the temperatures your vehicle normally operates in check your owners manual , and you're done. Then pour oil into the cylinder and weigh the cylinder and oil together. Skydivers enjoy one terminal velocity when they are in free-fall and another, much slower terminal velocity when they change their shape by releasing their parachutes.

## How to Measure Viscosity of Liquids

While there are a number of methods from which to choose in deciding how to measure viscosity, perhaps the least complicated involves dropping a ball into a clear container of the liquid for which you are trying to determine viscosity. Be sure to check the formatting, including capitalization, for the method you are using and update your citation, as needed. Viscosity is the measure of how resistant a substance is to flowing. F ull- automatic operation 5. Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies. Typically, fluids move faster away from the walls of the container, and fluids move more slowly the closer they are to the wall. Grades 9 - 12 Do you agree with this alignment? Water from the upper cup will fall into the lower cup through the hole.

## How to Determine Viscosity by 'Redwood Viscometer Experiment'

There are scientific ways to measure viscosity with a viscometer; but, a do-it-yourselfer's kitchen has most of the tools necessary to obtain a simple measurement of a motor oil's viscosity. You would also expect a sphere that has higher density i. This image shows two 4 ml silicone oil viscosity standard liquid drops in the process of coalescing to a single spherical drop. One way of measuring an oil's ability to lubricate is to measure its viscosity. The viscosity of a liquid depends on the temperature.

Using premium base oils for low volatility--to prevent evaporation--is one approach. They do remove some deposits, primarily solids. Thus, engineers must understand how fluids behave under various conditions. How to Choose Between Synthetic and Conventional Motor Oil Premium Conventional Oil: This is the standard new-car oil. The viscosity of a fluid is a measure of the fluid's resistance to flow.

When an object free falls through a fluid, at some point the force due to gravity is balanced by the resistance to shear by the fluid. Read the volume of oil from the graduated cylinder. The amount of friction that the sphere experiences as it falls will be related to its surface area, which is proportional to the square of the sphere's radius. The base oil package in any oil makes up anywhere from 70 to 95 percent of the mix, the rest comprised of additives. To measure the volume of a sphere, measure how much water the sphere displaces in a graduated cylinder. If you read your owner's manual, you'll know what the car manufacturer recommends for a brand-new vehicle. So resistance to viscosity loss shear stability is necessary to enable the oil to maintain the lubricating film between those parts.

Image courtesy of Marshall Space Center. Viscosity is one of the key parameters that materials scientists must measure to create accurate models predicting the best methods for materials production. First, fill your graduated cylinder with the liquid to be measured. The oil is a lubricantāa slippery liquid that allows the piston to slide freely within the cylinder. This experiment has many steps, but when followed correctly, they will allow you to calculate the viscosity of any liquid.

What happens to motor oil as the engine temperature goes up? Typically, the viscosity is reported at one of two temperatures, either 40Ā°C 100Ā°F or 100Ā°C 212Ā°F. Abstract The insides of a car engine get very hot when the engine is running. In this Article: Viscosity can be defined as the measurement of a liquid's resistance to flow, also referred to as a liquid's internal friction. Try testing many different liquids with different flow rates to see how their viscosities differ. All of these systems require a tremendous amount of engineering, which is the responsibility of automotive engineers. Viscosity of liquids can be measured with a special piece of glassware called a viscometer see Figure 1.
