Greg, The energy doesn't change. The bond energy in the water is constant regardless of pressure.
The cavitation issue is different. It is a phase change phenomenon, not a chemical change one.

Since we are speaking input air, I thought I might ask a somewhat elated question. Water gas shift. I know there are many that have talked about this, nd I understand the basics. However, here is the question. At what negative pressure ( negative in/wc) does the shift move down he temperature scale, to the point of being within the 1000 - 1200 c rea ? We all know that propeller cavitation produces steam in water that is 0 c (or there abouts), I have to assume (not being a chemist) that he same negative pressure effect would also apply to other principals hen dealing with water. -- Regards, Greg Manning, randon, Manitoba, Canada _______________________________________________ asification mailing list to Send a Message to the list, use the email address [email protected] to UNSUBSCRIBE or Change your List Settings use the web page ttp://lists.bioenergylists.org/mailman/listinfo/gasification_lists.bioenergylists.org for more Gasifiers, News and Information see our web site: ttp://gasifiers.bioenergylists.org/
