Sentences with phrase «gas density increase»

Since the satellite's velocity and the neutral gas density increase with decreasing altitude, the amount of drag quickly increases, causing a satellite to reenter Earth's atmosphere and either burn up or crash to the surface.

For less massive stars like the Sun the process that brings them into existence is quite well understood — as clouds of gas are pulled together under gravity, density and temperature increase, and nuclear fusion begins)-- but for the most massive stars buried in regions like RCW 106 this explanation does not seem to be fully adequate.

The motions of objects beyond the heliosphere showed that the charged gas, or plasma, that fills the space between stars should be much denser outside the border than within, and the Voyager team was at last convinced of an exit from the heliosphere thanks to a sudden increase in plasma density.

In this map of interstellar dust surrounding the sun, the white areas are nearly free of gas, while the dark areas contain gas of increasing density, suggesting something cleared out the region sometime in the past.

Gas and dust accumulated at the center increase the gravity and density of the core which generates energy to trigger nuclear fusion at 15 million degrees Celsius.

The Sun does not have a definite boundary as rocky planets do; the density of its gases drops approximately exponentially with increasing distance from the center of the Sun.

Finally burning a gas with a higher energy density would achieve an increase of power output.

EGR coolers decrease the temperature of hot exhaust gases recirculated into the intake manifold, which also increases the density of the exhaust gas.

A huge laser delivers a large amount of energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a very small size, increasing the density of the gases inside to much higher density than lead and heating it at the same time to very high temperatures required for fusion to occur.

If you reduce the rate of heat flux from the the planet to space by increasing the density of greenhouse gases and thus altering the thermal gradient, less heat will flow from the heat sink (ocean) to space.

If the energy extracted after the CO2 doubling is endemic to a smaller volume of air than before then the energy density of that volume has increased, and by the definition of Temperature in kinetic theory of gases, it is therefore now hotter as a result of the CO2 doubling.

If one cools the gas on the bottom and warms the gas at the top (relative to a gas with a DALR), if anything one expects to increase the density at the bottom compared to the top and shift the center of mass of the gas downhill while remaining (quasi-static process) in equilibrium.

Robert Brown continues: «As the bottom cools and the top warms the center of mass of the gas will indeed move down because the density of the gas at the bottom will increase while the density of the gas at the top will decrease.»

According to the ideal gas law PV = nRT, additional warmth (increased T) reduces density when P is held constant, namely by increasing V while leaving n (the number of moles and hence the mass) unchanged.

But wet lapse rate isn't about weight of atmosphere [in terms weight it's slightly lighter due lower density gas] but it's about an increase of energy [there is both kinetic and potential - but it's concerning change phase of water from gas to liquid - so kinetic energy which affects the pressure.

Increasing concentrations of greenhouse gases are expected to induce temperature decreases and a contraction of the upper atmosphere, resulting in a corresponding density decrease at a given height.

[53] Our results are consistent with theoretical predictions of the response of the thermosphere to increased concentrations of greenhouse gases, particularly with respect to the height and solar activity dependence of the density decrease.

According to the Hays Oil & Gas Global Salary Guide 2014, there have been government and company initiatives to increase the local oil and gas workforce, but these are hampered by the relatively low population densities in many oil and gas producing natioGas Global Salary Guide 2014, there have been government and company initiatives to increase the local oil and gas workforce, but these are hampered by the relatively low population densities in many oil and gas producing natiogas workforce, but these are hampered by the relatively low population densities in many oil and gas producing natiogas producing nations.
