But parallel gives the least deltaT temperature increase compared to a longer winding flow path, correct?
Yes, Heat Sink. My apologies!

I am trying to cool a linear electric motor. I want do design a custom water cooled heat sync into the support structure. The linear motor would be bolted to this with thermal paste between. Here is my basic question:
Is it better to have a flow path in one direction across the part? Better...
There is a huge heat treating opportunity I am working on currently, where I want to pressurize a vessel to a certain value in as little time as possible. We would like to use air instead of nitrogen, as the facility has a large central compressed air supply available. I am worried about the...
I have a two part question: No, this is not homework. Reference my other threads (http://www.eng-tips.com/viewthread.cfm?qid=354606).
1. Why is nitrogen used in autoclaves?
2. What is the temperature rise and fill time for a two tank connected system. Is adiabatic compression valid...
Thanks for all of the information everyone. All I'm really after is information on moving a set amount of compressed air from a higher pressure source into a vessel initially at atmospheric pressure. I can use a facility compressor, gas bottle, set of gas bottles, etc.
If I had a 2000psi...
The entire goal of my question is to minimize the fill time of a pressure vessel. If I can fill the vessel in 5seconds, great. 30seconds is too long for the application. 5-10 is ideal.
Here is an easier question. Imagine I have two tanks of equal size connected with a one way valve with...
It's not for a class. I have been out of college for 6years and am helping my father in law with a design problem. Don't believe me? Check out my website. He works at a plant with a 1000Hp air system that feeds all of the machines. They want to try an experiment in a steel cylinder of 28"ID...
I am trying to figure out how to calculate how long it takes to fill an air storage tank of a certain size to a certain pressure given a compressor HP. What calculation or method should I use?
Imagine a 1000HP central facility compressor connected to a 4" main distribution line. If I have a...
What design codes cover pneumatic actuators? What legal concerns are there if a design doesn't have an ASME BPVC stamp? See below details...
I am designing a custom quick locking pressure vessel that operates like a pneumatic cylinder - radial o-ring between upper half and lower half (not a...
Helium has a 5x multiple over air for thermal conductivity. Hydrogen is 7, but is flammable. We need the pressure of 10atm based on testing. We were just wondering if we used 70%air, 30% helium how it would work over 100/0, 80/20, 50/50, etc. The binary mixture will allow us to save on the...
What chapter or page in the text did you find this information? My father in law has a copy and I want to give him better guidance on where to look.
I really appreciate your help. We are looking to use helium or a combination of helium/air at pressure to cool some parts coming out of a heat...
I would like to understand if thermal conductivity is linear between a differing helium% / air% binary gas mixture and also how it changes at varying pressures between 1atm to 10atm. See below image...
