Investigatory Project
DETERMINING A LIQUID 'S
VISCOSITY USING MARBLES
An Investigatory and Exploratory Project
In Partial Fulfillment of
The Requirements in Chemistry
ABSTRACT The project is all about viscosity. Viscosity is a very important quality of liquids that scientists, engineers, and even doctors are frequently trying to measure and change. It is difficult, for example, to transport highly viscous crude oil through offshore pipelines, so scientists and engineers use a variety of methods to try and lower the oil 's resistance to flow through the pipelines. Likewise, in medicine, doctors try to keep blood viscosity in the correct range. If blood is "too thick," or viscous, a patient can develop blood clots. If blood is "too thin, ' ' or lacks viscosity, however, then the patient is at risk for bruising or bleeding events. Blood viscosity, like most things in medicine, has a happy medium. Volcanologists have a big interest in viscosity, too. The viscosity of molten rock or magma determines how easily a volcano will erupt, and what shape the lava flows and resulting mountains will take on. The researcher would observe that knowing the time it took to travel through the column of a liquid, the height of the column, the density of the sphere, and the density of the liquid, the researcher can then calculate the viscosity of the liquid with the viscosity equation. The researcher 's hypotheses were yes, the researcher can determine the viscosities of the liquids by using marbles. The researcher needed a graduated cylinder, ruler, pentel pen, five liquids (oil, water, hone syrup, vinegar, and soy sauce), stopwatch and five marbles. The researcher needed to get the average time, velocities, the delta 's and lastly the viscosity of the liquids by following the procedures in the methodology part of this project. The researchers results were that the dropped sphere method used was the basic way of find a liquid 's viscosity. The honey syrup
