I'm embarrassed to say that I need help explaining this real world observation. It's been too long since I've had my thermo class, and as an operations jack-of-all trades it's easy to forget the finer points.
We have a 13,000 gallon well-insulated tank. It is filled with nitrogen at...
Hello. I am doing some safety engineering work for an aerospace customer. They have a large high pressure gaseous hydrogen storage area that feeds other facilities. There is a large relief valve on the pipeline, as required by code. The RV dumps into a ~20 foot tall vent stack.

I have been hired to do some safety engineering work. In my exploration of the work site I have found numerous high pressure (up to 6000 psig) flex hoses without restraints. These are high quality stainless convoluted or stainless/PTFE hose, but many are decades old. They receive a visual...
I have a vacuum system which contains a flammable gas. I am trying to determine the explosion risks if this system were to be vented to atmosphere. I have calculated that once the pressure equilibrates (assuming no diffusion), the atmosphere is roughly:
10% O2
37% N2
48% He
5% H2
I guess I...
