    Hey guys, just a quick query; if a metal salt solution (essentially water for all intents and purposes) is very highly pressurised by a pump to levels such as those between 100 and 250 bar, and having started at 1 atm pressure, what will happen to the temperature? Obviously it will increase, but will it be a significant amount? And where can I actually find data to tell me what the temperature will be exactly after this pressure change? Thanks!!

    What kind of process are we discussing here? I suppose that'll depend on what type of pump we're talking about here, i.e. whether it's a rotating pump or a positive displacement pump.

    Once you know what kind of process it is there are standard equations that can be used to tell you the new temperature.

    Couldn't you use pV=nRT (think that's the equation any way) where p is pressure, v volume, n the number of moles of the substance, R being a constant and T the temperature? Then just take your starting temperature from your final temperature? I may be wrong as it's late ish and my mind isn't working particularly well...

    Oh, the pressure has to be in Pascals though, and R=8.31

    I might be wrong, but I'm fairly sure that's for gases.
