- A 1 88 M 6 Ft 2 In Man Has A Mass Of 86 Kg A Body Surface Area Of 1 9 M And A Skin Temperature Of 34 9 C Normall 1 (182.59 KiB) Viewed 54 times
A 1.88-m (6 ft 2 in.) man has a mass of 86 kg, a body surface area of 1.9 m², and a skin temperature of 34.9 °C. Normally, 80% of the food calories he consumes go to heat; the rest goes to mechanical energy. His emissivity e is 1 because his body radiates almost entirely nonvisible infrared energy, which is not affected by skin pigment. (Careful! His body at 34.9 °C radiates into the environment at 20.0 °C, but the environment also radiates back into his body. The net rate of radiation is Pnet = Pbody - Penvironment.) To keep his body's temperature constant, how many food calories should he eat per day if he is in a room at 20.0 °C and he loses heat only through radiation? food calories per day = C/day Does the answer seem reasonable? Yes ОО No
