water under pressure

can a cubic centimeter of water be compressed to less than that volume… in a simlar mannner that air can be compressed?

: can a cubic centimeter of water be compressed : to less than that volume… in a simlar mannner that air can be compressed?NO NO NO NO. Due to hydrogen bonding the molecules cant be put into a close packing array. Here let me keep it simple for you. Go out and BUY 2 balloons fill one with Air and the other with water PUNCTURE both. See the violent reaction of the Air (compressed) and the water plop. That is why we Master Plumbers HYDROSTASTCALLY test pressure vessels and piping systems. A hot water tank will expode when the water drains out leaving an air space and then heating it. Think about it huh amazing facts us Master plumbers have to know. Did you know that a low pressure hot water boiler is 160 psi and or 250 Degrees and a low pressure steam boiler is less than 15 psi. For some intreasting reading you may want to read some basic plumbing apprentice books. Lots of great stuff like hydrostatic pressures and pressurse temperature relationships. Friction losses. To prevent hydrolic shock (water hammer) in piping systems a lot of plumbers make an air chamber to act as a shock absorber. This air is a cushion JUST like in hydronic heating. As water gets hot it expands ( good ole pressure temperature relationship) In a closed H/W system we very well cant have pipes bursting all over the place and having this hot 250 DEGREE water flasing into steam killing everyone. So we plumbers/Steamfitters use AIR to take up for the expansion of the water. Air is very compressible. Here are some basic apprentice facts RE: water During freezing water expands 1/12 its volume. 1 Cubic foot of water at 62 degrees weighs 62.355 lbs. Water is most dense or heaviest at 39.1 deg. Frozen water exerts a pressure of 32,000 PSI. Fresh water will boil at 212 deg ( sea level) Salt water will freeze at 27 Deg. One cubic inch of water to one cubic foot OR 1700 Cu Inches of steam.. Water Pretty amazing stuff HUH? If you want more information please feel free to contact me Sylvan
