Some experiments that test the viscosity of liquids are the marble race experiment and the liquid race experiment. For the marble race experiment, you need a tall graduated cylinder, a marble, a stopwatch and the various... More »

Measure the centipoise, or cP, of a fluid using a viscometer. Centipoise is a unit of viscosity in the centimeter gram second system; in the International System of Units the pascal second replaces centipoise. More »

Test an oil pressure unit using a multimeter that is set to resistance with the engine off. Test the unit again with the engine running. The process takes only a few minutes. More »

Dropping a marble or ball bearing through a liquid is a simple method for measuring viscosity, while an Ostwald Viscometer is more complex and more accurate. The ball bearing method involves more rigorous calculations th... More »

The difference between high and low viscosity is the thickness of the material being measured. Low viscosity refers to substances that are thin, such as water, while high viscosity substances are thick. An example of a h... More »

Non-Newtonian fluids are those that behave differently than Newtonian fluids do with regard to viscosity. Typically, stress causes non-Newtonian fluids to alter their flow patterns or viscosity. The stress can cause the ... More »

Newton's law of viscosity is a constitutive equation that describes how a fluid resists attempts to move through it. It holds true with some liquids and fails in others. Therefore, it is not considered a fundamental law ... More »
