why not?? does it form some sort of coagulate?? usually oil and water don't mix well - at least that's my understanding. I know they add some additives to fuel to make water mix better with fuel so that it won't freeze up fuel lines
The vacuum dehydration process (Figure 3) lowers the partial pressure, which assists in removing the water from the oil. Just like boiling water on top of Mount Everest, lowering the pressure allows water (and other volatile materials) to boil at a much lower pressure.
Figure 3. Vacuum Dehydrator
At the typical pressures used by most vacuum dehydrators (25" to 28" of mercury), water boils at 120°F to 130°F. By heating the oil, typically to 150°F to 160°F, water is vaporized inside the dehydrator, without causing excessive oil degradation due to thermal and oxidative stress. In most dehydrators, the air is warmed and dried prior to being passed over the oil, encouraging the water to transfer from the oil into the air. To maximize the process, the oil is thinned to obtain the greatest amount of surface area exposure possible. This is achieved by allowing the oil to pass over a number of surfaces internally in the vacuum chamber, or by creating an umbrella spray within the chamber through which the dry air passes.
The real benefit of this process is its ability to remove dissolved water and other low-boiling liquid impurities such as fuels and solvents. The removal of dissolved water makes it ideal for systems requiring low target levels of moisture. It is particularly useful in environments where large volumes of oil are at risk from the process or system, such as in steam turbines or paper mills. In fact, for lightly additized oils such as turbine oils and transformer oils, a vacuum dehydrator can remove as much as 80 percent to 90 percent of dissolved water, achieving water levels as low as a few ppm.
The main disadvantage of vacuum dehydrators is their cost and comparatively low flow rate. Because of the cost, many companies chose to rent dehydrators on an “as-needed” basis rather than purchase them.
The main advantage of vacuum dehydrators is that they offer the ability to remove moisture to very low levels. The greater the volume of oil and water, and the lower the target moisture level, the more cost-effective vacuum separation becomes.

That's a reasonable enough note to sum it up by - everyone looks for something different.
I would say that the meaning of life is the meaning you give it.
Someone once told me that there was a book that contained the meaning of life...
life - noun - the condition that distinguishes organisms from inorganic objects and dead organisms, being manifested by growth through metabolism, reproduction, and the power of adaptation to environment through changes originating internally.

Yes, well. I was deliberately missing the point, you see.
Certainly, the biological purpose of life is to pass on genes but that's not all there is to do with it, nor is there any universal "meaning" to it that can be proven, even if there are people who think their book of choice contains such answers.
I guess I'm being flippant again, like when I got bored and tried to see how many Beatles lyrics I could fit into that Theopia discussion without anyone noticing. The answer was quite a lot, including large parts of Strawberry Fields. I didn't get quite bored enough to try I am the Walrus though.

Yup, after all I am he as you are he as you are me and we are all together.
Very strange - you think you know me but you haven’t got a clue. I say "high", you say "low". It's all wrong - that is, I think I disagree. We'd all want to change the world, but I look at all the lonely people.
Let me tell you how it will be; Look for the girl with the sun in her eyes. The minute you let her under your skin then you begin to make it better. It really doesn't matter if I'm wrong.
