Hydraulics

[Wes]

My son, an 8th grader is interested in hydraulics and is planning to prepare his science project on the effect that different oils and other liquids have on the lifting power of a hydraulic jack. That is his plan. Do any of you with extensive experience with hydraulics have any other suggestions on what he might research regarding hydraulics for his science project?

Thanks

Wes I don't know if these links will help but they should put you in the right direction.

I've got a few more if these aren't what your looking for! Good luck the last link is an open board ask that question there and be prepared for some pretty in depth answers! But some great information

Since all liquids tend to be almost uncompressible, the major difference in hydraulic fluids have more to do with temperature, viscosity, compatability with seals and clutches and lubrication than ability to lift a load.

Wen's post reminded me of something that might work for a science project: the affect of air entrapment on hydraulic performance.

Here is the link I should have posted the first time http://www.fpef.org/fpeftext.html Sorry for the mixup.
