Cool man; you're welcome.

As the old saying goes; if I save one engine - it will be worth the time right? LOL

these are NOT the interchangeable terms. They are both fluids, but this is misleading otherwise.

Do you think it makes it harder to understand the meaning?

I was trying to make it a lighter article.... but if you guys think it detracts from the Law's meaning - maybe I should change it.

I personally do, mostly from what was pounded into me in my Fluids classes. I just think that someone unfamiliar might misunderstand it. I mean think how many liquids are even compressible.

They all are - it just takes a LOOOOOOT of force. ;)

I'll clean it up. Thanks for the feedback.

well not compressible with any known amounts of force.

although a machine that compressed water into ice (which expands in the solid state) would be interesting.

Not so much. Imcompressible flow (air) is what we use for conveince however air itself is a compressible fluid (hence why we have to change formulas when we start getting into principles that deal with flow faster than the speed of sound). This is also the sonic boom/carpet boom in effect.

Also some other compressible fluids are silicon brake/clutch fluid. Any suspension, and if any water or steam particles are boiled into a gylcol matrix will also become compressible. Also given enough pressure or force fluids will not necessarily turn into a solid, but more than likely will compress into a plasma, which unfortunately is still a fluid.

For a fluid to turn into a solid would take a large amount of gravitational force (not mechanical, at least not with current technology). This is why we have a solid iron core at the center, yet a very hot liquid outter core. http://en.wikipedia.org/wiki/Structure_of_the_Earth
