Sentences with phrase «reduced air density»

These hotter temperatures will reduce air density and make it much more likely weight restrictions are needed for flights taking off during the hottest parts of the day.

Not exact matches

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).

A primal approach can help achieve quality sleep as proper nutrition (reduced sugar, reduced chemical additives, reduced fillers, and increased nutrient density), outside play (small natural doses of vitamin D, exercise, imaginative play and reduced time with electronics), clean air (less household toxins and fewer chemicals to breathe in), and love and support all positively influence your child's ability to sleep well.

Yes, low air density (usually caused by high altitudes) will reduce engine output significantly.

The supercharger is fed through a charge cooler that uses the Demon's air conditioning system to reduce the intake temperature and increase its density and therefore power.

Key differences between the RS and other more timid Focus models include a new low - inertia twin - scroll turbocharger with a larger compressor (to deliver much greater airflow) and a monstrous intercooler to maximize air charge density, a less restrictive intake design, and a large bore exhaust system with an electronically controlled valve to optimize back pressure and reduce offensive noise.

Two air - to - water intercoolers reduce compressed air temperature for maximum intake charge density.

The intercooler helps reduce the temperature of air entering the engine, increasing its density for greater performance.

It follows that air rising and expanding into a region of lower pressure need do no work on the surrounding molecules because it simply expands into the additional space made available by the reducing density gradient.

The pressure will increase, reducing density of packets of air which will rise.

This reduces the molar density of the air.

At the surface, evaporation takes energy from the water surface or from the surface on land and reduces the density of the air parcel above so that the air parcel becomes lighter and can rise.

Thus a parcel of air into which water vapour is injected will rise without any change in ambient temperature.The reduction of density from surface upwards is what initially reduces air pressure as measured from the surface.

Evaporation injects potential energy into an air parcel in the form of latent heat thereby reducing density and weight to below the global average.

ii) If pressure within an air parcel rises then the contents expand to occupy a larger space but that decreases density and weight which reduces pressure at the surface below.

If the loss of water from the air (condensation) reduces the volume, then isn't it also increasing the density?

First it increases the local pressure, then that drives air outwards from the heated volume, and that reduces density.

With zero latent heating, yes, the pressure would reduce, the density would go up as air fills in the deficit, and clouds would sink.

That reduces the density by 1.2 % in comparison with dry air.

Evaporation initially reduces the density of the air within a convective cell below the global average and condensation simply restores the density within the cell to the global average so it is trite to suggest that the condensation process additionally reduces density and surface pressure outside the parcel.

When firn is buried beneath subsequent snow accumulations, density increases as air spaces between the crystals are reduced by mechanical packing and plastic deformation until... interconnected air passages between grains are sealed off into individual air bubbles (Herron and Langway, 1980).
