The fraction of the energy flux received which is reflected into space is the albedo of Venus, av, which is about 0.76. The fraction of the energy flux which is absorbed is then (1-av) = 1. - 0.76 = 0.24. So the amount of energy actually absorbed by Venus in each second is Lv = (1-av)Ev. Lv = (1-av)Ev = ___________________ ergs/s
The fraction of the energy flux received which is reflected into space is the albedo of Venus, av, which is about 0.76. The fraction of the energy flux which is absorbed is then (1-av) = 1. - 0.76 = 0.24. So the amount of energy actually absorbed by Venus in each second is Lv = (1-av)Ev.
Lv = (1-av)Ev = ___________________ ergs/s
And next calculate the effective temperature of Venus:
Tv4 = (Lv/(4pdv2))/s = Lv/(4spdv2) = __________________ K4
and taking the square root of Tv4 twice in succession we get the effective Temperature Tv:
Tv = [Lv/(4spdv2)]0.25 = _________________ K
Calculate Venus' emittance assuming that the Venus' actual temperature, Tvr, is 472o C = 745 K:
ev = Lv/(4pdv2s Tvr4) = __________________ .
