Heat transfer
Please answer quick with clear work
Thank you

2. For a flat blackbody surface, there is a fluid flowing in parallel with h 25W/m2K and T-300K. When the surface reaches to thermal equilibrium (hint: gcom Grad), what is the temperature of the surface? If the temperature of the surface reaches to 400K, what is the ratio of the radiation heat flux and convection heat flux for this blackbody surface? (25 PTS)
