Human body heat generation
WebThe mean surface area of a human is approximately 1.7 m 2, and a reasonable approximation for the BMR of a human is about 100 W (2000 kcal/d). Hence MB ≈ 60 W/m 2 of body surface area. Any exercise on top of the BMR requires more power. To maintain a steady flow of heat from the human body’s core (37 C) to the environment, the skin has … WebThe human body is quite inefficient at using the energy derived from metabolic processes to create external work. Approximately 70 to 95% of energy (depending upon the …
