Assignment #2 for marking
1. Put 10 W of thermal power into one end of a 30 cm long, 2 cm diameter aluminum rod, painted matt black. Assume the ambient temperature is a uniform 20 C, and the convection constant kc = 5 W/m2/K. In your submission, include your code and a properly labelled graph of steady-state temperature versus position on the rod.
2. Estimate kc for a horizontal rod to get a better number than my guessed 5 W/m2/K. You will have to do some digging around the internet for this. Show your working and where you got the information from.
Make sure that you indicate your answers appropriately, e.g. "The RMS velocity of air at 273K is v_rms = ... ".
