All, I have a small vessel that I suspect (know) is leaking. I anticipate the leak rate to be higher the higher the pressure is inside the tank. What I wanted to do with the equipment I have was connect the vessel up to a small pump and pull a vacuum inside the vessel and have a ball valve...

Thanks for the responses everyone. Looks like we are both correct to a degree. At lower temperatures we can sum and be accurate but at very high temperatures there are so many variables that come in to play that it would not be a simple addition.

All, I have been having a discussion with a coworker about temperature rise over ambient. We have two opinions but have not been able to find any test data or proof for either case. If we have a bar of any material and we apply a current through it(lets pretend 5000A), we know the bar will heat...

All nice ideas. I am playing around with several of them right now sketching a few things out. Hopefully one of these will inspire me to make something cheap and effective. Appreciate all the input.

Its not just a nice level area. Its fairly rough terrain and gravel in many places. Prefer not to drag it around in case of damage etc. Sometimes our skids are painted but typically galvanized. I was trying to come up with something that would not have wheels at the very end of the skid. Reason...

This could possibly help. Let me know. http://www.ittco.ir/en/images/stories/catalog/irantechnic-single.pdf

Hey guys, I am brainstorming and trying to come up with an idea on how (at my work place) we can move large structural skids around the yard without having to use (2) forklifts (one on each end of the skid). Its only a matter of time before one is dropped. I am talking about large W12x53# skids...

Okay. This is exactly what I planned on doing and thought I had everything correct. Thanks for the help guys. It is much appreciated. Always best to double check. If you have time to do it twice you had time to do it right the first time.

I am trying to determine the characteristic curve of a small unknown pump. I have set this up with the large tank of water with piping connected to the pump. I have a pressure gauge directly before the inlet of the pump and also right after the discharge. After the second pressure gauge coming...
