That's absolute viscosity, but it'll do.

Crap.

Water has an absolute viscosity of 1.12cps @ 15 degrees, making Copper Sulphate over 10 times more viscous than water.

So long as the solution is less than 10 times as viscous, it offers some advantage due to its higher thermal conductivity, but above 10x more viscous it holds the boundary layer enough to outweigh any advantage conferred by its higher conductivity.

At least that's for a couple of impingement cases I was working with.

So, no-go then...
