Possible Heat Transfer Question

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
