Assuming you had 60 gallons of water at 150 degrees F and 500 psig in a vessel that cannot deform, how can you figure out how the pressure is affected by temperature. If the temperature dropped to 100 degrees F, what would the new pressure be?

Is there a formula for liquids like the ideal gas law,
(p1/t1 = p2/t2)? How can we solve something like this?

Thanks

Should I assume this is not homework?
It is the vapor pressure of water at 100 degrees which is 0.95 psia.

Hint: water is virtually incompressible, or is it?

Welcome...
..My statement at this point.. and I hope you already know and have thought of this... You aren't really going to build a non-deforming vessel completely charged with a liquid having zero gas expansion cushion in the design, are you??? If so, I hope there is a piston or blow out valve somewhere! Or.. else I hope you test it somewhere safe away from living things.

I'll let one of the thermo expansion experts answer the actual question.





The worst suggestion of your lifetime may be the catalyst to the grandest idea of the century, never let suggestions go unsaid nor fail to listen to them.
