Part A In this problem you will consider the balance of thermal energy radiated and absorbed by a person. Assume that the person is wearing only a skimpy bathing If the surface temperature of the skin is taken to be Tbody = 30"C, how much thermal power Pri does the body described in the suit of negligible area. As a rough approximation, the area introduction radiate? of a human body may be considered to be that of the sides of a cylinder of length L = 2.0 m and circumference Take the emissivity to be e = 0.6. C =0.8 m. Express the power radiated into the room by the body numerically, rounded to the nearest 10 W. For the Stefan-Boltzmann constant use View Available Hint(s) 7 = 5.67 x 10 8 W/m2/K+ AEd 8 ? Pro = W Submit Part B Complete previous part(s) Part C Complete previous part(s) Part D Find Pnet, the net power radiated by the person when in a room with temperature Troom = 20"C. Express the net radiated power numerically, to the nearest 10 W. View Available Hint(s)
