[QUOTE="Jpcol1990, post: 4997930, member: 535661"] [h2]Homework Statement [/h2] The filament is 30 cm long and has a diameter of 1.5mm. The filament is drawing 15 watts and has an emissivitity of 0.9. The surroundings are at 283 k. Estimate the surface temp of the filament in K. [h2]Homework Equations[/h2] N = Wcycle/Qin, W cycle = Qhot - Q cold. [h2]The Attempt at a Solution[/h2] I'm not sure how to relate the lengths. I think 0.9= Wcycle/15 watts. But not sure what to do after I find Wcycle. Any help would be appreciated! [/QUOTE]
