I'm looking for some number to use for a heat transfer coefficient of bare wire in still air. but not having much luck.
This number just needs to get me into the ball park - I know it would be rather complex to solve with precision.
Think of it this way - I have a length of wire dissipating x...
I have a graph which shows the rate of cooling of a tent from about 35 deg C to 15 deg C, it looks like this:

How do I work out the convective heat transfer coefficient of the tent from this data?
Thanks for any help
I'm having a bit of trouble with a Thermal Physics excercise. I was wondering if anyone knew what the definition of the heat transfer coefficient was? I can't find anything about it in my textbook (Thermal Physics, 2nd ed., C.B.P. Finn).
More specifically, the assignment at hand says to find...
Hi,
Does anyone know the heat transfer coefficient (&lambda in W K^-1 m^-1) of oil. I'm looking for this for polyolester, but if you have data of another oil, tha't would be fine!
Thanks,
