ABSTRACT

Viscosity is a property of a liquid and is defined as the resistance of a liquid toflow. This research is to determine the viscosities of motor oils (10w – 40w, 20w –50w), vegetable oil and honey using the fall sphere method. The viscosity of honeywith 4.44Ns/m2was found to be the highest and that of vegetable oil having a valueof 0.002861Ns/m2 is termed the lowest. The viscosities of motor oils (20W-50W )and (10W-40W) were found to be 0.00468Ns/m2 and 0.00374Ns/m2 respectivelyshowing that motor oil ( 20W – 50W) is preferable for lubrication due to its highviscosity.
