- Homework Statement
- A student is trying to decide what to wear. His bedroom is at 20°C. His skin temperature is 35°C. The area of his exposed skin is 1.50 m2. People of all races have skin that is dark in the infrared, with emissivity about 0.900. Find the net energy loss from his body by radiation in 10.0 min.
- Relevant Equations
- q = ε σ T4 A
σ = 5.6703 10-8 (W/m2K4) - The Stefan-Boltzmann Constant
I do not know where I am doing wrong. I asked a tutor, he said I was doing it correctly.
Below is my work. Please help!
Net loss by radiation in 10.0 mins is 74.8 kJ
