#9. The normal human body has an average core or interior temperature of 37C. At a skin temperature of 34 C, how much heat is removed through conduction? Assume a thermal conductivity of unperfused (i.e. bloodless) tissue of 18 (Cal x cm)/(m^2 x hr x C), 3 cm thickness of the tissue between the interior and the exterior of the body and 1.5 m2 total surface area of the human body.

#10. If the human body needs to get rid of 150 Cal of heat per hour through conduction alone, at what temperature should the skin be if a core temperature of 37C is maintained? Assume a thermal conductivity of unperfused (i.e. bloodless) tissue of 18 (Cal x cm)/(m^2 x hr x C), 3 cm thickness of the tissue between the interior and the exterior of the body and 1.5 m2 total surface area of the human body.
#9 "q=\\lambda\\cdot\\frac{\\Delta T}{\\Delta x}\\cdot A=18\\cdot\\frac{37-34}{3}\\cdot 1.5=27(Cal\/hr)" . Answer
#10 "q=\\lambda\\cdot\\frac{\\Delta T}{\\Delta x}\\cdot A\\to t=37-\\frac{q\\cdot\\Delta x}{\\lambda\\cdot A}="
"=37-\\frac{150\\cdot3}{18\\cdot 1.5}=20.333(\u00b0C)" . Answer
