Sentences with phrase «net radiative heat transfer»

From this layman's perspective you are discussing NET radiative heat transfer between non-gaseous objects thus infering wide band land wave radiation is emitted / absorbed by the surface of each object.

In any introductory engineering heat transfer text, you will see that the net radiative heat transfer between two objects (1 and 2) is given as:

I pointed out that cooler objects do not warm warmer objects because the net radiative heat transfer would be negative and because it would imply that the cooler object spontaneously loses entropy without doing any work.

It is not the infrared emission that cools the surface as in the so - called radiative equilibrium models because the net radiative heat transfer surface to air is about nil, but the evaporation whose thermostatic effect can not be overstated: increasing the surface temperature by +1 °C increases the evaporation by 6 %; where evaporation is 100 W / m ², this removes an additional 6 W / m ² from the surface.

Not exact matches

«in an isotropic non GHG world, the net would be zero, as the mean conduction flux would equalize, but in our earth it is still nearly zero» if the atmosphere were isothermal at the same temperature as the surface then exactly the downwelling radiation absorbed by the surface would be equal to the radiation of th surface absorbed by the air (or rather by its trace gases) and both numbers would be (1 - 2E3 (t (nu)-RRB--RRB- pi B (nu, T) where t (nu) is the optical thickness, B the Planck function, nu the optical frequency and T the temperature; as the flow from the air absorbed by the surface is equal to the flow from the surface absorbed by the air, the radiative heat transfer is zero between surface and air.

That gravity is responsible for the 33K in unexplained heating and contrary to the assumptions of the radiative transfer model, increasing the weight of N2O2 in the atmosphere will increase the surface temperature, as more and more molecules are packed into a smaller volume, resulting in a net increase in energy per cubic meter of atmosphere at the surface, which we measure as an increase in temperature.

Therefore it is only the net energy flows which need be considered when estimating the radiative heat transfers in the diagram.

I made the suggestion that the NET radiative flux should be compared with other heat transfer processes; you think otherwise.
