As referred to in NFPA, what class of fuel is No. 2 diesel?
NFPA, International Fire Code, etc. refer to fuels as Class IIIB, or Class II, and so on. Where can I find a simple list in laymen's terms of what fuels fall into which classes.
Why is a by-pass needed around a steam PRV? If the PRV is off-line, and the by pass is used, doesn't this let HP steam through where only MP or LP steam was meant to go?
That said, if I have 4" PRV and a 3" PRV in parallel, what size should the by pass be?
Thank you.
