What I have thus far:

3 modes of heat transfer: free convection to the air, radiation to the surroundings, and conduction to the blue painters tape used to attach the thermistor.

Convection:

I used the Rayleigh Number and Nusselt Number for cylinders and laminar flow. Followed by Newton's Law of Cooling to calculated power: 3.585W.

Radiation:

I went straight to Newton's Law of Cooling for radiation. Using the emmisivity constant for nichrome. 0.501W

Conduction:

I wrapped standard blue tape around the wire 3 times. So, using Fourier's Law I calculated the power dissipation to be: 0.734W

In total: 4.82W. Pretty far away from 13.15W. I feel like I am missing something major. I can post the equations I used if you think that will help.

I appreciate any help anyone can provide. Unfortunately, faculty at my university won't give me the time of day!
