Question

What is the total rate of radiation of energy from a human body with a surface area of 1.45 m² and a surface temperature of 30°C (303 K)? If the surroundings are at a temperature of 20°C, what is the net rate of radiative heat loss from the body? The emissivity of the human body is very close to unity, irrespective of skin pigmentation (e=1).

Step 1

45 \, \text{m}^2 \) - Surface temperature of the human body, \( T_{\text{body}} = 30^\circ \text{C} = 303 \, \text{K} \) - Temperature of the surroundings, \( T_{\text{surroundings}} = 20^\circ \text{C} = 293 \, \text{K} \) - Emissivity of the human body, \( e = 1 Show more…
