Measure Viscosity With Marbles

Can you imagine trying to swim in a pool of.

Measure viscosity with marbles.

Racing marbles to measure viscosity. Google classroom create assignment create announcement. Although it involves some knowledge of algebra a basic experiment can measure the time it takes for a round sphere to. In this paper we have demonstrated that lycopodium coated marbles have an effective viscosity larger that water drops.

High viscosity fluids have a lot of resistance to changing their shape so the marble takes longer to fall. Understand the variables in the viscosity equation. 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. Retrieve the marbles from the strainer and wash and dry the marbles and the graduated cylinder.

In our experiment the marbles took longer to sink when dropped into the jars filled with corn syrup and honey than they did when dropped into the jars filled. To our knowledge the effective viscosity of marbles has never been considered yet. For example honey is more viscous than water. Viscosity is a measurement of a fluid s resistance to change or deformation or more simply put how thick it is.

Design an experiment to test how the viscosity of honey changes with temperature. Of course some liquids are more viscous than others. Dropping a sphere in a liquid is one of the oldest and easiest ways to measure viscosity. By measuring how long it takes the marble to fall and how far it travels you can figure out the liquid s viscosity.

You won t need to do any calculations in this activity but you will get to. The more viscous or thick a liquid is the longer it will take for an object to move through the liquid. By amy cowen on august 27 2015 3 00 pm. But a do it yourselfer s kitchen has most of the tools necessary to obtain a simple measurement of a motor oil s viscosity.

Density is mass per unit volume of an object and is designated with a p in this equation you need to measure the density of both the sphere p s and the liquid p l it is passing through the radius of the sphere a can be found by measuring the circumference of the sphere and dividing that by 2π. The viscosities ratio simply scales as r l r and l being respectively the radius of the marble and l the characteristic thickness of the. There are scientific ways to measure viscosity with a viscometer. Honey is a great example.
