Sentences with phrase «lower air density»

ie does a slightly lower density of air mean a slightly lower ground level temperature (temperature normally decreases with height at the lower air density), so that in reality adding CO2 and subtracting more O2 actually causes miniscule or trivial global COOLING, and the (unused) ability of the changed atmosphere to absorb radiation energy and transmit it to the rest of the air is overruled or limited by the ideal gas law?

In view of the low density of the intake air at loads below supercharging level and when coasting, its rotors are free - running and the amount of power required to drive them is low.

Design highlights include: New front - end styling with distinct differences between LS / LT, RS and SS, including the fascia, grille, LED dual - element headlamps and reshaped hood (ZL1 retains its airflow - optimized front - end styling) SS - specific front fascia with «flowtie» open bowtie grille emblem and aero - enhancing air curtains, specific headlamps with new LED signature and extractor - style hood RS Appearance Package available on LT adds unique polished black grille with Galvano Chrome lower inserts, new LED headlamps with LED signature light bar, specific rear fascia with rear diffuser and 20 - inch wheels New rear fascias for all models, with specific diffusers on RS and SS when equipped with Dual Mode Exhaust New LED taillamps with a more sculptured evolution of Chevrolet's signature dual - element design; red lenses are featured on LS and LT, with RS, SS and ZL1 featuring dark - tinted neutral - density lenses New 20 - inch wheel designs on RS and SS Turbo 1LE The new Camaro Turbo 1LE joins the V6 1LE, SS 1LE and ZL1 1LE to round out Camaro's lineup of 1LE track stars.

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.

The hotel was designed with a low density and minimal environmental impact and continues to be environmentally - friendly by using wind and solar energy as well as not using air conditioning but instead designing natural cross-ventilation into each room.

Re: # 32 «Natural [free] convection is due to the low density of the air caused by the lighter water vapour.»

Natural convection is due to the low density of the air caused by the lighter water vapour.

Maximum incoming solar heating occurs there but the greatest temperatures are near 50 km where the low density air requires very little energy to raise its temperature (think KE = 1/2 mv ^ 2 and fewer collisions with fewer air molecules yield greater v).

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.

Due to the low density and (dynamic) viscosity of air, it is almost impossible for moving air to be in a laminar flow regime.

They run on low - density air, air that rises, condenses out the moisture and rewarms the air, which rises deep into the troposphere.

The low density air rises.

My favorite possibility is that upwelling cold water west of South America lowers the ocean and air temperatures, and consequently raises the density of the atmosphere there.

The upshot of the differences in air density that manifest between 400 hPa and 50 hPa is fast displacement of low density air that travels to the top of the atmosphere in a cone that surrounds the very cold dense descending air from the mesosphere.

Ice crystals that grow by deposition have much lower densities than solid ice because of the air pockets occurring within the volume of the crystal.

Low pressure, high temperature air will always have the lowest density and rise to the top, and because air is a poor conductor of heat the air will stratify hot on top down to cooler on the bottom — an inverted lapse — until one gets to a turbulent zone that turns over diurnally.

The point is that the formula for the DALR comes from the assumption that the air heats down low and rises, expanding adiabatically into the air above it (doing work against its increased pressure / density) and cooling as a consequence, a process that only «stops» when there is a uniform lapse between the warm bottom and the actively cooled top.

But perhaps that isn't good example, as one could also say it's due to the low density of air - the lack of buoyancy, which is also sort of saying the lack of gravity affecting it much.

Adding the influence of water vapor concentration to the density profile makes the difference between the densities of the two cases a little larger, because water vapor lowers the density as H2O molecules are lighter than average for dry air.

If the air is low in water vapour then the overall motion will likely be dictated by the classical temperature / density balance.

A man - made vortex reaching miles into the sky would act much like a very tall chimney, where air density and temperature effects can be harnessed to produce electricity from low - energy content gases, such as those rejected from a cooling tower.

Technically, we'd need to correct for the lower atmosphere temperature in the Arctic (increasing density compared to the rest of the earth), and the lower atmosphere thickness at the poles (decreasing air mass compared to the simple NOAA approximations for all values from the equator to the poles).

EUV is mainly consumed above 100 km in the thermosphere where the air density is low.

If you stop that convection or increase the density of the air you can increase altitude of the condensation layer, but as it is, the cloud base will lower and there will be an increase in mid level convection.

1) Air is heated at the warm surface, it expands and has a lower density than the rest of the near surface atmosphere.
