Re: [Vo]:diathermic oil for heat transfer
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

Sorry if this was already mentioned, but Rossi said on his blog this week that he might use a diathermic oil for heat tranfer in later versions of the eCat. I cite this as an example: http://www.paratherm.com/InfoServices/index.asp?vendorid=6010gclid=CIWOoM_R96sCFULrKgodmX3PuA Harry

Hi Terry, Not really, keep up the good work and valuable sometimes humorous comments you are providing.

Re: [Vo]:diathermic oil for heat transfer
looking at heat transfer fluids. Glycole (http://goo.gl/haL10) Note! The specific heat capacity of ethylene glycol based water solutions are less than the specific heat capacity of clean water. For a heat transfer system with ethylene glycol the circulated volume must be increased compared to a system with clean water. In a 50% solution with operational temperatures above 36 oF the specific heat capacity is decreased with approximately 20%. The reduced heat capacity must be compensated by circulating more fluid. 2011/10/20 Terry Blanton hohlr...@gmail.com: On Thu, Oct 20, 2011 at 3:42 PM, Harry Veeder hveeder...@gmail.com wrote: lately my brain has been crashing, so I don't read all the messages.
