A person infected with the SARS-CoV2 virus is running a fever with an internal body temperature of 103 deg * F(39.4 deg * C) This raises the person's skin temperature to 36.5 C. The person is standing unclothed in a room with an ambient temperature of 21.0 If the temperature of the person's skin is maintained at 36.5 deg * C solely by the energy obtained from the metabolic conversion of food, how many Calories would this person have to consume per hour? Assume heat is lost only by radiation, and the surface area and emissivity of the person's skin are 1.5m ^ 2 and 0.800 , respectively.

The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 230 J/s. The energy is transferred a distance of 1.8 × 10-3 m through a body whose surface area is 1.7 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin.
The giant hornet Vespa mandarinia japonica preys on Japanese bees. However, if one of the hornets attempts to invade a beehive, several hundred of the bees quickly form a compact ball around the hornet to stop it. They don’t sting, bite, crush, or suffocate it. Rather they overheat it by quickly raising their body temperatures from the normal 35 C to 47 C or 48 C, which is lethal to the hornet but not to the bees . Assume the following: 500 bees form a ball of radius R=2.0 cm for a time t= 20 min, the primary loss of energy by the ball is by thermal radiation, the ball’s surface has emissivity ´=0.80, and the ball has a uniform temperature. On average, how much additional energy must each bee produce during the 20 min to maintain 47 C?

Overall, 80% of the energy used by the body must be eliminated as excess thermal energy and needs to be dissipated. The mechanisms of elimination are radiation, evaporation of sweat (2,430 kJ/kg), evaporation from the lungs (38 kJ/h), conduction, and convection. A person working out in a gym has a metabolic rate of 2,500 kJ/h. His body temperature is 37°C, and the outside temperature 22°C. Assume the skin has an area of 2.0 m2 and emissivity of 0.97.
