The thermal conductivities of human tissues vary greatly. Fat and skin have conductivities of about 0.20 W/m · K and 0.020 W/m · K respectively, while other tissues inside the body have conductivities of about 0.50 W/m · K. Assume that between the core region of the body and the skin surface lies a skin layer of 1.0 mm, fat layer of 0.50 cm, and 3.2 cm of other tissues.

You have a cylindrical beverage container that has been sitting in your hot car all day, and it has heated up to a temperature of 50.0°C. It will now be placed into your refrigerator to cool down by natural convection. The air temperature inside your refrigerator is 4.0°C (assume P = 1.00 atm). Based on this initial condition, calculate whether you should place the beverage container standing upright, or laying on its side in order to cool it faster. The beverage container has a diameter of 65.0mm, and a height of 100.0mm; ignore any end effects and radiation.
