Suppose you are outside on a cold day with no gloves. Assume your hands have an area of 0.01 m2. The temperature of your hands is 36 C and the temperature outside is 0 C. a) If it is calm and the heat exchange coefficient is h = 5 W/m2· K , what is the rate of heat transfer in kJ/s from your hands? b) If it is windy and the heat exchange coefficient is h = 200 W/m2· K , what is the rate of heat transfer in kJ/s from your hands?
