THE EFFECTS OF S.A.E. NUMBER, TEMPERATURE, PRESSURE, AND TUBE LENGTH ON THE VISCOSITY OF MOTOR OIL
The purpose of our experiment was to determine the effects that four different factors, S.A.E. number, temperature, pressure, and tube length, had on the viscosity of motor oil. Using a steel ball bearing and a plastic tube, we calculated the velocity for how long the ball took to fall through the oil. Using the velocity and densities calculated for the steel ball and the three different oils, we were able to calculate the viscosity of the motor oil. Our data showed that temperature had the greatest effect, followed by pressure, then S.A.E. number, and finally tube length which had the least effect on the viscosity.
