A fire fighter (approximated by a two-sided black surface at 310 K 180 cm long and 40 cm wide) is facing a large fire at a distance of 10 m (approximated by a semi-infinite black surface at 1500 K). Ground and sky are at 0 °C (and may also be approximated as black). What are the net radiative heat fluxes on the front and back of the fire fighter?
q = ε.σ.T4.A.Fij
The Attempt at a Solution
I have problem identifying the view factor in this case. Can anyone help me? Thanks.
