Step 1
Power = Energy/time Energy = Power x time Energy = 0.35 W x 2 hours x 3600 seconds/hour Energy = 2520 J Show more…

A person with a surface area of 1.20 m2, and a skin temperature of 27 °C, is in a room that is at a temperature of 16.2 °C. The emissivity of the skin is 0.895. The Stefan-Boltzmann constant is 5.67 x 10-8 W/(m2·K4). (a) How much power (power is the energy per second) is radiated by the person? Keep 2 decimal places. Watt (b) How much power is absorbed by the person from the surroundings? Keep 2 decimal places. Watt (c) What is his NET Power loss? Report as a Positive value. Keep 2 decimal places. Watt
