Default water volumes and temperature question

OK Thermodynamics studs... is there a simple formula to determine what temperature the resulting volume of liquid will have if two or more different-sized volumes of liquid at differing temperatures are mixed?

i.e. one gallon of water at 40 F plus one gallon at 80 F plus two gallons at 200 F would result in four gallons at what temperature?

[(1 x 40) + (1 x 80) + (2 x 200)]/4 = 130F, assuming you don't lose any heat when mixing.

Bike N Brew is right - as long as none of it has grain in it.

As long as the cold water isn't frozen, yes. Now if it's ice, it equalizes lower than you'd expect because it takes energy to melt ice.
