It depends on what you are referring to. Generally some ways of reducing friction are by using smoother surfaces, using fluids with lower viscosities, using grease or any lubricant, using rollers/wheels, using ball bearings, and with objects like cars and planes- these are usually made with streamlined shapes.
sity hydraulic fluids
There are many possible reasons. Some are: They could be in different fluids. The fluids could be flowing in different directions. The depths of the fluids (and slope of the beds) could be different.
Convection
The different strengths of a magnet are determined by the magnetic fluids it produces. The strengths of a magnet are seen in motors, refrigerators and dynamos.
cps stands for centipoise.They have different viscosities.
High Viscosities
Suspensions: substances with similar viscosities, but different specific weights.
Because they have different viscosities and densities.
They have different Viscosities which does not allow the two to mix.

sity hydraulic fluids
Their volumes are equal. But their colors, weights, masses, viscosities, and nutritional contents are different.
Look in the owners manual, but it recommends 10w-30, however with newer synthetics you can use different viscosities...
its viscosity depends on what it's going against
The one that is recommended for your car, check the owners manual for this information. Many cars use different oil viscosities depending on the engine type.
Unless you are operating in extreme cold or hot temperatures you do not have to use different weights. A multi grade oil will work all year round.
