The Wondering Wanderer

A Single Fin of 3 cm diameter and 20cm Height is erected vertically in a horizontal plane. Given that the ambience temperature is 25 degree celsius, determine the heat lost by radiation and convection if the Fin as a radiation coefficient of 0.5 and is at a temperature of 50 degree celsius. If a collar of 1 cm diameter and 10 cm height is not oscillating up and down the fin. Determine the net rate of heat gain. Take friction coefficient as 1 and the mass of the collar as 0.5 kg ....................................................................................... Sweat :P

hmmm... But really. . . I wonder what is he trying to test us. Maybe perhaps the concepts or what. . . but. . . The is machines. basically this is a modules which you can just do all the question but still have no idea if you are right or not. . . at least for me. I am a mortal still. I have not achieved "godlike" status yet. But oh well. . . Let's make a brave prediction HR - - A+*. Basically I just crap and I tot I wrote very good crap Materials - - B? I drop 20 marks on this. Oh well. . . I love to screw myself. Machines - - B- / F? F is the prof is really pissed with that sentence. . . oops. . . That's all folks. :P
