Consider a person sitting nude on a beach in Florida. On a sunny day, visible radiation energy from the sun is absorbed by the person at a rate of 30 kcal/h or 34.9 W. The air temperature is a warm 30 ℃ and the individual’s skin temperature is 32 ℃. The effective body surface exposed to the sun is 0.9 𝑚2. (Assume this same area for sun absorption, radiative transfer, and convective loss. Is this a good assumption?)

Yes, You can assume whatever you wish for.
