salt water as coolant

[71skylark]

Does anyone here know what salt does to the thermal conductivity of water? I've found that saturated salt water won't freeze in my freezer at -5F.

[Kingslayer]

No but I do know what it does to the metal parts inside pumps.

Salt water? :eek: :eek: :eek:
Perhaps if you don't mind your water block being eaten away.

salt used in water increases the range of the water, it will boil at 105 and freeze at -5, a better idea would be to use antifreeze. the salt would not be healthy for the pump

OK, what is the cheapest form of bulk alcohol I can get, cheaper than $5/gal. I've found that getting methanol for $5/gal usually involves about $6/gal for shipping. And the only place I could find it for that price was worldwideracingfuels.com as race gas. Where do you racers get your methanol?

Use isopropyl(rubbing alcohol) or antifreeze. Methanol is a little better, but not by a whole lot. Antifreeze should do nicely.

I think Antifreeze is the best solution, altough if you are doing experiences ot may become expensive, so use 20% alcohol on you water and it should work well enough.
