Sentences with phrase «different heating values»

When we talk about natural gas as a heating fuel, it has two different heating values.

Not exact matches

«The biofeedback system successfully maintained a wide range of ETR values in different species, while it also is capable of distinguishing between conversion of light into heat and damage to the photosynthetic machinery as causes for decreases in light use efficiency,» the authors said.

Dodge has four trim levels with different features, for instance, the American Value Package has 17 - inch steel wheels and heated side mirrors.

Setting aside the effects of the deep ocean, etc, — ie just using a single unified reservoir's heat capacity — and using only fast feedbacks (I didn't introduce any slow feedbacks anywhere in this particular series of comments), the expectation based on physics is that each delayed response T curve (each of which must correspond to a different value of heat capacity, for the same ECS) must have a maximum or minimum when it intersects the instantaneous response curve (my Teq value)-- maximum if it was below Teq before, minimum if it was above — because it is always going toward Teq.

C is not constant for the dT» / dt equation to apply because heat penetrates through different parts of the climate system (different depths of the ocean in particular) over different time scales (also, if T» is supposed to be at some reference location or the global average at some vertical level, T» at other locations will vary; C will have to be an effective C value, the heat per unit change in the T» at the location (s) where T» occurs)

Actually, though, most of the OLR originates from below the tropopause (can get up around 18 km in the tropics, generally lower)-- with a majority of solar radiation absorbed at the surface, a crude approximation can be made that the area emitting to space is less than 2 * (20/6371) * 100 % ~ = 0.628 % more than the area heated by the sun, so the OLR per unit area should be well within about 0.6 % of the value calculated without the Earth's curvature (I'm guessing it would actually be closer to if not less than 0.3 % different).

They actually say something different:» For example, most mid-latitude studies show that the heat island intensity (the difference between the temperature of the warmest location in the city and the background rural value) of the near surface air layer reaches its maximum a few hours after sunset on calm.

We present an analysis to illustrate why temperature values at specific levels will depend on wind speed, and with the same boundary layer heat content change, trends in temperature should be expected to be different at every height near the surface when the winds are light, as well as different between light wind and stronger wind nights.

The table below will give you a general idea of the investment value, based on average U.S. sunshine and different backup water heater types (a backup heater is needed to heat the water when the sun doesn't shine).

In principle, you do not need to specify how much the different heat transport processes contribute to the temperature changes as long as you can find the total value of h.

If the heat transfer patterns were very different for the Eemian it might not have much value as a guide.

GWP is a value used to compare different greenhouse gases that trap heat in the atmosphere.

The average around the equator of the eastward wind in the upper tropospheric layer of the idealized atmospheric model of Suarez and Duffy 1992, for several different values of the strength of an imposed tropical heat source.

As you point out, there are many different combinations of heat transfer processes and states of the atmosphere and surface that can provide that same value of tropopause radiative fluxes.
