The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.57 m, a width of 44.0 cm and a length of 23.5 cm.
Calculate the power emitted by the human body.

Fortunately our environment radiates too. The human body absorbs this radiation with an absorbance of 97.0 percent, so we don't lose our internal energy so quickly. How much power do we absorb when we are in a room where the temperature is 23.5 °C?

How much energy does our body lose in one second?

this is a thermodynamics course We want to model energy and mass balance issues involved in strenuous exercise, for example the running of a marathon. Suppose a 70 kg marathon runner runs at an ≈8 minute/mile pace, completing the 26.2 mile race distance in 210 minutes, or 3.5 hours. a.) Physiological measurements indicate that the total power consumed by an average weight runner (70 kg) at a pace of 8 minutes/mile is about 900 kcal/hour. What is the total energy...
