A person stands in front of a fire at 650 C in a room where air is at 5°C. Assuming the body temperature to be 37°C and a connection coefficient of 6 W/m2K, the area exposed to convection as 0.6m2, determine the net heat low from the body. The fraction of radiation from the fire of 1m2 are reaching the person is 0.01.
