please help this is a problem that combines a lot of cases and assumptions and I am lost.

i need to understand it step by step if it is possible

( 25 points) A horizontal, opaque surface at a steady-state temperature of 77C is exposed to an airflow at temperature of 27C with h=28W/m2.K. The emissive power of the surface is E=628W/m2, the irradiation is G=1380W/m2, and the reflectivity is 0.4 . a. Please draw a schematic and write assumptions b. Determine the transmissivity and absorptivity of the surface c. Determine the net radiation heat transfer rate (q " rad ) for the surface. d. Is the heat transfer to or from the surface? e. Determine the convective heat transfer (q"conv) for the surface. f. Determine the total heat transfer flux for the surface. g. Is the heat transfer to or from the surface
