What is the rate of heat transfer by radiation, with an unclothed person standing in a dark room whose ambient temperature is 22.0ºc . the person has a normal skin temperature of 33.0ºc and a surface area of 1.50 m2. the emissivity of skin is 0.97 in the infrared, where the radiation takes place.

W

Explanation:

= Temperature of the room = 22.0 °C = 22 + 273 = 295 K

= Temperature of the skin = 33.0 °C = 33 + 273 = 306 K

= Surface area = 1.50 m²

= emissivity = 0.97

= Stefan's constant = 5.67 x 10⁻⁸ Wm⁻² K⁻⁴

Rate of heat transfer is given as
