Compare the rate of heat loss from a human body with a typical energy intake from consumption of food (5440 kJ/day). Consider the body as a vertical cylinder 30 cm in diameter and 175 cm high in still air. Assume the skin temperature to be 37°C. Consider the emissivity at the skin surface as 0.4 and neglect, sweating and effect of clothing. The ambient air is taken at 13ºC.
