Confused about thermal conductivity units
Confused about thermal conductivity units
(OP)
I am setting up a steady state thermal analysis of a model. I am using FEPipe and the help file says this...
"For steady state or transient the thermal conductivity is a required input. If this value is
omitted, (as it often is), the user will get unpredictable thermal solutions. The standard units
are Btu/sec/in/deg.F for Imperial units....
ASME as well as all other books and documents I have report the thermal conductivity as BTU/(sec*in*degF). Are these units interchangeable? I feel like if I assign the constant (in this case 15.46) to the BTU term, because all the other values represent a single unit (1)...the units should be interchangeable (15.46 BTU/1sec/1in/1degF). I feel like an idiot not being able to work through this...but I'm stuck on it

I'm struggling to see what you are having problems with.

RE: Confused about thermal conductivity units
If the software documentation is correct, how do I get from BTU/(sec*in*degF) to Btu/sec/in/degF? I have been trying to walk through dimensional analysis and I cant get the units to work out...this is why I think they are the same unit, just written out in a different way

I've also seen it as BTU s-1 in-1 F-1
