Q9: Consider a person standing in a room at 23°C Determine the total rate of heat transfer from this person if the exposed surface area and the skin temperature of the person are 1.7 m2 and 32 C, respectively, and the convection heat transfer coefficient is 5 W/m2 - "C. Take the emissivity of the skin and the clothes to be 0.9, and assume the temperature of the inner surfaces of the room to be the same as the air temperature. Answer: 161 W
