A person wearing light clothes (k clothes = 0.03 W m⁻1K⁻¹) with a thickness of 1 mm has a total surface area of 1.6 m² They have a 0.5 cm layer of body fat insulating their core body (kfat = 0.02 Wm⁻¹K⁻¹). If their core body temperature is 36 °C, and the external air temperature is just 5 °C then: What is the heat transfer coefficient for the person's body fat?
