Hi, I'm trying to do some figuring on vapor pressures. If one were to take two plates heated to 220F and press water between them in a press that exerts 100psi, what would the resulting vapor pressure of the water be? Now, what temperature would you heat the plates to if you were using a press that exerts 625psi and wanted to achieve the same vapor pressure as with 220F and 100psi scenario? Is this possible or am I going down a dead end? Is there a formula like (x) psi results in an increase of (y) temperature? Lastly - does longer time exposure to a constant heat and pressure continue to build vapor pressure, or does the vapor pressure remain constant once achieved? Any answers or formulas that might be used to solve this would be very greatly appreciated :-) I hope I didn't post this in the wrong section. Thank you!
