Hi, I’m in a heat transfer course and wondered could you help me with the question below:
The sun can be modeled as a sphere of radius R=695500 Km with surface T=Ts =5778 K.
Assuming that the emissivity of the solar surface is unity, estimate the total rate of heat Q (W) generated by subsurface unclear fusion in the sun, assuming all is radiated2 into the surrounding space at 4K.
Given data: Surface temperature Ts = 5778 K
Surrounding temperature Tsurr = 4 K
Radius of the sun ?r? = 695500 Km = 6.955*10^8 m
Emissivity =1 Now the rate of heat generated will be given as: 4…
