As the meteor enters the atmosphere it is assaulted with atmospheric ram pressure. Ram pressure is the pressure exerted on the object and causes a drag force. A meteor produces a shock wave generated by the rapid compression of air in front of the meteor.

What would happen if lightning struck a meteor?

The lightning would travel through the meteor or through the plasma sheath around it. Some of the surface of the meteor may melt, though this will happen to a meteor anyway. Otherwise the meteor would be unaffected. The stress of atmospheric entry is much greater than any stress created by the lightning.

What is the typical thermal adiabatic efficiency of a sliding vane compressor?

In discussing adiabatic efficiency, it is best to first define efficiency. In its broadest terms, efficiency can be defined as the ratio of work output to work input normally expressed as a percentage. With regard to a compression application, one measure of the efficiency of a compressor is the adaibatic efficiency (Volumetric Efficiency being the other). Adiabatic Efficiency is the ratio of the amount of horsepower required just to compress a particular gas (Adiabatic Horsepower) divided by the total brake horsepower required for a praticular type of compressor to accomplish the desired compression. Note that Adiabatic Power is the same regardless of the type of compressor used because it is a function of the physical properties of the gas being compressed, and not the type of compressor doing the work. In other words, it takes a specifc amount of energy to compress a specific volume of gas to a particular pressure and this energy is the same no matter what technology you use to accomplish the compression. Adiabatic HP is the numerator of the equation and is the same no matter what kind of compressor is used. The denominator of the equation is total brake horsepower (BHP) and it is the total power required for a compressor to accomplish the desirder compression. This will be a larger number as BHP includes adiabatic power plus all the other energy required by the compressor to overcome other losses requiring energy such as drive losses, mechanical friction losses, intake/discharge valve losses, heat exchanger losses, lubrication system power, etc. Therefore, to answer the question specifically would require information on the specific gas being compressed, flow, pressure, atmospheric conditions, etc. To answer the question in general terms, the rotary vane type compressor will typically have a higher adiabatic efficiency than screw compressors and reciprocating compressors by virtue of the fact that other losses from friction, lube systems, valves, etc. which tend to be significant with screws and recips are not substantial and sometimes not present at all with vane technology. As such, vane compressor total BHP is normally lower than other technologies resulting in higher adiabatic efficiency. Another reason vane machines often have higher adiabatic efficiency is that they are limited to a maximum compression ratio of approximately 4.5 to 1, (depending on the type of gas and the application requirements). As is documented in Marks' Standard Handbook for Mechanical Engineering, as compression ratio increases, both adiabatic efficiency and volumetric efficiency decrease on screws and recips. Therefore, for discharge pressures up to approximately 125 psig, the vane technology, even in a two stage system, will likely be more energy efficient than other compression technologies. The above is a broad answer to a specific question and the degree to which the efficiency is greater (or not) will vary with the specifics of the application. Adiabatic efficiency is however, a good measure of efficiency and a good indicator of how energy efficient equipment will be once in operation. All the compression technologies mentioned are viable and proven and some are better suited than others depending upon the specifics of the application. For example, as noted above, the vane machine is well suited for relatively high flows and for compression up to about 125 psig. For processes requiring compression above 125 psig discharge pressure, the vane technology is not suitable and screws or recips are likely the more appropriate technologies. Finally, in addition to power cost, buyers should also other factors that impact the cost of ownership such as parts, service, and maintenance requirments when considering compression equipment.


What would happen if a meteor hit a tornado?

The meteor would pass through the tornado, without being affected in the least.


Why is the saturated adiabatic lapse rate lower than the unsaturated adiabatic lapse rate?

The saturated adiabatic lapse rate is lower than the unsaturated adiabatic lapse rate because when air is saturated with moisture, the release of latent heat from condensation offsets some of the cooling that would normally occur as the air rises. This results in a slower rate of temperature decrease with height compared to unsaturated air.


What is the shape and structure of a meteor in space?

Technically, a "meteor" is the streak of light caused by a space rock fallingthroughthe atmosphere and being heated to incandescence by friction and compression. So there are no meteors in space.You're probably wondering about a "meteoroid", which is a space rock drifting through space, which would become a meteor if it ever hits the atmosphere. We don't know, because we've never had a chance to examine one close-up in space. But we expect that they would all be different, depending on how and where they were formed - or were blasted apart by the collision of other larger space rocks.


Do meteoroligists predict meteor showers?

No. Meteorologists study weather. An astronomer would predict meteor showers.


Is the adiabatic lapse rate higher when its cloudy or not?

There are two types of adiabatic lapse rates...wet and dry. (wet is also referred to as saturated or moist) To the extent that the cloudiness your question refers to represents saturated air, then no, the wet adiabatic lapse rate would be lower (approximately 1.5C/1000') than the dry adiabatic lapse rate (approximately 3C/1000').


When is the meteor shower in Colorado springs 2017?

In 2017, the annual Perseid meteor shower peaked around August 12-13. In Colorado Springs, the best viewing conditions would have been late at night and into the early morning hours during this time. Clear skies and minimal light pollution would have provided the best experience for observing the meteors.

How happen iso thermal compression in screw compressor?

Isothermal compression in a screw compressor occurs when the gas is compressed at a constant temperature, typically achieved through effective heat exchange. As the gas is drawn into the compressor, it is compressed by the intermeshing rotors, and cooling mechanisms, such as external heat exchangers or internal cooling circuits, help dissipate heat generated during compression. This helps maintain a stable temperature, ensuring that the compression process remains isothermal rather than adiabatic, which would lead to higher temperatures and reduced efficiency. Proper management of heat is crucial to maintain high performance and efficiency in the compressor.
