In a steel annealing furnace, two gray plates (emissivity 0.7 and 0.9) exchange thermal radiation. If the plates are not parallel and the view factor from Plate 1 to Plate 2 is 0.3, how does this view factor influence the net radiative heat exchange compared to otherwise identical parallel plates?
It decreases the net radiative heat exchange because less radiation reaches the opposite plate.
It increases the net radiative heat exchange because radiation becomes more concentrated.
It eliminates the influence of surface emissivity on the radiative heat exchange
It makes the radiative heat exchange the same as that between parallel plates
It decreases the net radiative heat exchange because less radiation reaches the opposite plate.
