Boiling Point H20 @ 600 psi?

  1. Feb 10, 2010 #1
    Boiling Point H20 @ 600 psi????

    According to the psychometric chart boiling point of water @ 600 psi is 252 C.

    I have a chamber with water inside (in forms of weight measured drops). I am purging CO2 at 600 psi in the chamber. After am heating the chamber to 155 deg C expecting the water to stay.

    It boils or just goes away - I have no idea why it is happening?

    Could anyone please explain what are the potential reasons that could be happening?

    Is it boiling or just evaporating? How big are the drops and how big is the chamber? According to a steam table, the vapor pressure of steam at that temp is 80psi and the density is 0.2 lb/ft^3. http://www.efunda.com/Materials/water/steamtable_sat.cfm

    I think just evaporating because I can't see it boiling.....The chamber size is quite big...and water measured would be like 100 mg max.

    You might want to review Dalton's Law.
