Question

Define viscosity, Flash point and Pour point of a lubricant.

Answer 1

the friction between the layers of a liquid is known as viscosity the substance which has less viscosity will flow fast

Answer 2

Answer:

It decreases (thins) with increasing temperature and increases (or thickens) with decreased temperature. The benefits of oils with a higher viscosity is that a general increase in viscosity at higher temperatures results in lower oil consumption and less wear, which is profitable for the environment.
