Heat Transfer Questions & Answers  




I don't understand what you mean. Please explain better.




In this case, the Kelvin degrees used for $h$ can be written as Celcius degrees because convection heat transfer is function of temperature difference only and a difference in Kelvin is exactly the same as a difference in Celcius degrees.




If you use $k$, $\rho$ or $c$ elsewhere in your problem, then to be consistent you should compute $\alpha=k/\rho c$ and not take it from the tables.




Hm I think I explained this in class. I am not sure what you don't understand. Tell us what exactly is confusing you..
