Consider a person standing in a room with a temperature of 22°C throughout moment. It is observed that the interior surfaces of the walls, floors and ceiling of the house are at an average temperature of 10 °C in winter and 25 °C in summer. Determine the rate of heat transfer by radiation between this person and the surrounding surfaces, if the exposed surface area and the average temperature of the outer surface of this are 1.4 ?2 and 30 °C, respectively.

Consider a person standing in a room with a temperature of 22°C throughout
moment. It is observed that the interior surfaces of the walls, floors and ceiling of the
house are at an average temperature of 10 °C in winter and 25 °C in summer.
Determine the rate of heat transfer by radiation between this person and the
surrounding surfaces, if the exposed surface area and the average temperature of the
outer surface of this are 1.4 ?2
and 30 °C, respectively.
