Viscosity, wading through the numbers
Viscosity, wading through the numbers: Simply put, viscosity is the measure of resistance to flow, the higher the number the greater the resistance. Seems easy enough until one discovers that there are several ways to describe the same viscosity. Stationary or mobile? An easy way to look at it is to consider the application: is the application stationary or mobile? A general rule of thumb would be if the application is stationary then the ISO viscosity grade (VG) applies and if it is [...]
