What is Density and Viscosity of Motor Oils about?

This document summarizes an experiment to determine the viscosity of three motor oils (5W-30, 10W-30, and 20W-50) using the falling sphere method. Tables of data collected are presented, including the mass and diameter of the sphere, diameter of the cylinder, height of the liquid, temperature, average time for the sphere to fall, and mass of 10 mL of each fluid. Calculations of viscosity are shown for each motor oil. Sources of error and ways to improve accuracy are also discussed.
