An average-sized man is sitting in a big tanning room. The tanning radiation from the room walls is controlled by setting the temperature of the walls of the room. Neglecting the radiation heat exchange between the air in the room and the man's body, calculate the maximum temperature in °C to which these walls can be set so that the body temperature of the man does not exceed its normal value of 37 °C. A thermometer kept in the middle of the room reads 35 °C. Assume equilibrium conditions and use the following data is given. Body surface area of an average male human being = 1.9 Average emissivity of the human skin = 0.97 Stefan-Boltzmann constant = 5.67 X 10-8 Convective heat transfer coefficient of still air = 10
