Effects of propylene glycol on heat transfer efficiency

AI Thread Summary
The discussion focuses on calculating the heat loss efficiency of propylene glycol compared to water in heat transfer fluids, with water considered as the baseline at 100% efficiency. Participants emphasize the need for reliable data points to formulate an equation rather than relying on arbitrary figures. Resources, including a link to Dow's thermal conductivity data for aqueous solutions, are shared to aid in the research. The importance of using precise terminology in searches for relevant information is also highlighted. Overall, the conversation centers on understanding the impact of propylene glycol on heat transfer efficiency.

I'm trying to calculate the heat loss of efficiency due to increasing the mixture of propylene glycol in a heat transfer fluid compared to water.. For this I'm saying that water has a heat transfer efficiency of 100% (relative only)

Im looking for multiple data points to create an equation not just random numbers.

I searched Google for propylene glycol solution thermal conductivity

Thanks! I tried googling but was not using the right words!

Thread 'I need a concave mirror with a focal length length of 150 feet'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
