Tom, Thank you. I think the amessage was for all vorticians not just me! So I reply back to the list.
I was looking for a comparison of heat transfer fluids specs, do you know if there is any? What is the Max operating temperature in particular? I understand that if you want to keep liquid phase with glycole you need high pressures at temperature above 200°. Some oil seem to have a much higher boiling point. mic Il giorno 21/ott/2011 01:02, "Tom Andersen" <tom.ander...@gmail.com> ha scritto: > The heat capacity is 1/2 that of water for these materials, but they can > run hotter, so for instance oil at 500C is taking away about 3 times the > heat of water at 99C. > > --Tom
