It's essentially a cooler with two chambers that facilitates condensation, and takes in air as the bike moves, which is then slowed and cooled down by barriers that allows it to condense and form water, which is channelled and collected in the bottle.

And the process of condensation where moist air forms clouds is the process by which the latent heat is released — warming the lower troposphere while cooling the surface.

BUT that if we continue to add CO2 to the air, the air has the added heat capacity to get warmer, IF and ONLY IF driven by the sun, but rapidly come to equilibrium with the ocean, by means of rain and the daily heating & condensation of the water vapor feedback mechanism.

Heat (not latent heat) is removed prior to condensation by conversion of kinetic energy to potential energy which then provokes condensation and when the phase change occurs the release of latent heat causes the air parcel to rise a little further with additional conversion of KE to PE until it reaches the correct lapse rate temperature for its height and then it stops rising and begins to descend.

The open cycle consists of the following steps: (i) flash evaporation of a fraction of the warm seawater by reduction of pressure below the saturation value corresponding to its temperature (ii) expansion of the vapor through a turbine to generate power; (iii) heat transfer to the cold seawater thermal sink resulting in condensation of the working fluid; and (iv) compression of the non-condensable gases (air released from the seawater streams at the low operating pressure) to pressures required to discharge them from the system.

An aposite example is «Potential energy of atmospheric water vapor and the air motions induced by water vapor condensation on different spatial scales» which can be found at http://www.bioticregulation.ru/common/pdf/neraz-en.pdf.

Heated by condensation on the rise, the descending dry air would adiabatically heat up at 9.8 deg C per 1000 meters and so that it would rapidly become warmer than surrounding atmosphere having a standard lapse rate of 6.5 deg C per 1000 meters.

This would seem to indicate that condensation is greatly helped by these nuclei, but, depending on conditions, they are not absolutely required for condensation to begin, especially in subfreezing air.

The presence of cloud condensation and ice nuclei in air parcels is tested by using cloud chambers in which controlled temperatures and relative humidities are specified.

I am thinking the solar energy invested in evaporation (in this case, of irrigation water) is matched by the energy released during condensation; energy released to the atmosphere, raising the temperature of the air.

This is particularly the case in areas where a change in SST causes the formation of fog, since much of the sea temperature change is taken up, not by a corresponding air temperature change, but by the condensation of water.

Condensation then restores the weight of the air parcel back to the global average by removing the latent heat.

Ascending air cools The only heating is from solar infrared (absorbed by water vapour) and condensation (of water vapour); the heating in the altitude explains the Ch.

The UNtopia theory (Sahel reforestation and bass pond) is similar the condensation driven winds, only the trees to be planted by the scientists provides a natural surface temperature inversion with cool moist air, the wind bags, er scientists, provide the initial kinetic as they rush to publish.

capt.d., the rain is formed by condensation in ascending air.

(The air heated by condensation will continue to rise, but there can't be «vacuum» around the condensation, the colder air at that level will come in to replace any lighter hotter air rising, and colder is heavier so will sink which increases the pressure at the surface.)

The local pressure reduction pointed to when condensation reduces volume is instantly offset by mass flowing into the original volume from the surroundings and the energy released is not enough to make the air parcel and the liquid contents lighter than air containing water vapour.

So on condensation, under the still rising hotter lighter air carrying on doing its thing and perhaps adding new layers, there would be the accompanying volume and temperature decrease of that first previously rising lighter volume now heavier liquid water and added to by the adjacent volumes of heavier colder air flowing beneath the still rising lighter hotter and into the space now available on condensation of its neighbour, which all now being heavier will increase the pressure at the surface as they all sink together displacing the lighter.

As said on cards n ° 1, n ° 6 and n ° 15, for an atmosphere in a gravitation field, the tropospheric lapse rate is dT / dz = — g / (Cp + Ch) where g = 9,8 m / s ², Cp = 1005 J / kg, and Ch summarizes the effect of the heating of the air (1) by absorption of the solar infrared by water vapour or liquid and (2) by the condensation of the water vapour.

They end the chapter «This proves that water vapor condensation in any adiabatic process is necessarily accompanied by reduced air pressure.»

JimD, «capt.d., the rain is formed by condensation in ascending air.

The cloud condensation nuclei counter measures the concentration of aerosol particles by drawing an air sample through a column with thermodynamically unstable supersaturated water vapor that can condense onto aerosol particles.

This can't be the case for the obvious reason that pressure is determined solely by the mass of air and water above it, which is unchanged by condensation.

This paper actually proposes that the sensible heat released by condensation warms the dryer air to a point where it becomes even lighter than air containing water in vapour form.

@PP: «This proves that water vapor condensation in any adiabatic process is necessarily accompanied by reduced air pressure.»

Pekka, «The influence of condensation on the volume and density of moist air is also understood by every scientist working on these issues.

I was unhappy with my comment and so have been looking it up and have confirmed that the energy released by condensation warms the air.

Remove the water vapour and the air which lacks it must descend.The heat released by condensation can never heat it enough to make it lighter than air containing water vapour.

The influence of condensation on the volume and density of moist air is also understood by every scientist working on these issues.

I would not however accept that this rephrasing is equivalent to AM's phrasing «water vapor condensation in any adiabatic process is necessarily accompanied by reduced air pressure» because the latter carries with it the implication that if significant condensation occurs at a fixed altitude, with no other effect such as failling rain, then there is a reduction of air pressure.

Somewhat late, but if condensation drives winds by a decreasing the number density of water vapor in the air, then as clouds form they should shrink in size due to the negative pressure.

It seems to me that the low pressure at the surface created by the expansion of rising gases would begin to alter at whatever height there was condensation, so while it may appear to still be low pressure at the surface this is about to change as condensation gets into its stride and the colder air around the condensation will also be getting heavier.

It is not possible for the sensible energy released by condensation to cause enough heating to prevent the air from contracting cooling and descending so the net result must be an increase not a decrease in surface pressure.

1g / kg of condensation releases enough latent heat to warm the air by 2.5 C. 2.

Then Nick's dry air motor example is not relevant: it only proves that dry air circulated by motor is NOT a condensation - induced circulation.

A detailed and very accurate calculation of the atmospheric flows of moist air must take into account also the effects related to the volume taken by water vapor both when water vapor is added by evaporation and when it's removed in condensation, but these effects are very minor corrections and not a source of anything significant.

The lapse rate of nonrising air — commonly referred to as the normal, or environmental, lapse rate — is highly variable, being affected by radiation, convection, and condensation; it averages about 6.5 °C per kilometre (18.8 °F per mile) in the lower atmosphere (troposphere).

Temperature changes induced by sun and oceans drive air circulation changes which drive changes in every aspect of climate including convection, conduction, evaporation, condensation, precipitation, windiness, cloudiness, albedo and humidity as regards both quantities and distribution.

Populations around the globe have so far, unfortunately, accepted the «commercial air traffic condensation trail» official lie that is fed to them by agencies and the vast majority of government sponsored academia.

Much more energy is transferred via the processes of evaporation / condensation and freeze / sublimation at relative constant air temperature than can be accounted for by changes in air temperature.
