Hey I've got this question and the answer that is giving is 219.12 but i keep getting 319 could someone please help me out here's the question.
Consider a person standing in a room. The room air temperature is
maintained at 22OC at all times. The inner surface of the walls, floors and
the ceiling of the room are observed to be at an average temperature of
10OC.
Determine the total rate of heat transfer from this person if the exposed
surface area and the average outer surface temperature of the person
are 1.4 m2 and 30OC. Take the convective heat transfer coefficient to be
6 W/m2 OC and the emissivity of the human skin to be 0.95
any help would be great
