Question
For the human body, what is the rate of heat transfer by conduction through the body’s tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is $2.00\textrm{ C}^\circ$ , and the skin area is $1.50\textrm{ m}^2$ . How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)
The rate of heat loss is $20 \textrm{ W}$. On a daily basis, this is 17% of the daily food energy intake when there's a temperature difference of $2.00\textrm{ C}^\circ$
