Consider a person whose exposed surface area is 1.7 m2, emissivity is 0.9, and surface temperature is 32°C. Determine the total rate of heat loss from that person by radiation and convection in a large room having walls at a temperature of 18oC. The convective heat transfer coefficient is 5 W/m2.K.
