IMC 510.4 prohibits the recirculation of hazardous air. But if the concentration is below 1%, which is less than 25% of the lower flammability limit of 4%, would the air then be considered hazardous per IMC? Please keep in mind that the battery cabinets with, VLRA batteries, are being exhausted...
I found another thread that asks a similar question but I did not see an answer to the question.
I have a situation where there is a battery room that has a dedicated exhaust system with hoods over the battery cabinets. The problem is that the current design has more supply air than exhaust air...
I do believe the other responses, it is more that I wanted to stop my hijacking and start a new thread dedicated to this topic.
I was also hoping to get more information on how to prove that our statements are true or at least conservative.
It has been a short time since I posted the tread...
Your right IFRs, it may be better to include the maximum pressure and temperature to better describe the systems that this calc can be used for.
There is no small task that I cannot over complicate.
I am working on a calculation that someone else started and I will be cleaning up and finishing.
The calculation is to determine general pipe support spans for pipes of a certain material, maximum temperature of 110F, and 1" through 2" in diameter. He used a statement in the calc that the...
Sorry for the hijacking, but I wanted to get your input.
The attempt of this calculation is to develop standards for our company for allowable pipe spans for straight runs and distances between support and elbows for pipes under a certain temperature, say 100F. The reason we wanted to leave out...
It sounds like you, prex and BigInch, are skirting a question that I deviates from this topic a little.
Background...I have a generic calculation that our company is wanting to use to determine allowable pipe spans depending on certain situations. Someone else started the calc and in the...
I am trying to qualify some pipe supports that will require a reinforcing pad (repad) due to the hogh forces acting on the pipes.
We have a structural T support and trunnion support that require a repad. The T supports are sliders and the trunnion support is an anchor.
I need to determine how...
