Consider the white frost problem. Recall that on a still night, the heat lost by the dew on the grass by radiation is equal to the energy gained by convection. Let us consider a patch of dew on the top of the grass for which all the radiant energy leaving it goes to outer space. Further, if we assume the dew to be a black body and outer space to be a black body at -40°F, at what air tempera- ture will the dew temperature drop to 32°F if the convective heat transfer coefficient between the dew and the air is 5 Btu/hr-ft²°F?

Transcribed Image Text:Consider the white frost problem. Recall that on a still night, the heat lost by
the dew on the grass by radiation is equal to the energy gained by convection.
Let us consider a patch of dew on the top of the grass for which all the radiant
energy leaving it goes to outer space. Further, if we assume the dew to be a
black body and outer space to be a black body at -40°F, at what air tempera-
ture will the dew temperature drop to 32°F if the convective heat transfer
coefficient between the dew and the air is 5 Btu/hr-ft²°F?
