There are three possible relationships between temperature and pressure in a volume of gas undergoing compression: </p> <ul><li><a href="/w/index.php?title=Isothermal_process&action=edit&redlink=1" class="new" title="Isothermal process (not yet started)">Isothermal</a> - gas remains at constant temperature throughout the process. In this cycle, internal energy is removed from the system as heat at the same rate that it is added by the mechanical work of compression. Isothermal compression or expansion is favored by a large heat exchanging surface, a small gas volume, or a long time scale (i.e., a small power level). With practical devices, isothermal compression is usually not attainable. For example, even a bicycle tire-pump gets hot during use.</li> <li><a href="/wiki/Adiabatic_process" title="Adiabatic process">Adiabatic</a> - In this process there is no heat transfer to or from the system, and all supplied work is added to the internal energy of the gas, resulting in increases of temperature and pressure. Theoretical temperature rise is <i>T</i><sub>2</sub> = <i>T</i><sub>1</sub>·<i>R<sub>c</sub></i><sup>((<i>k</i>-1)/<i>k</i>))</sup>, with <i>T</i><sub>1</sub> and <i>T</i><sub>2</sub> in degrees <a href="/wiki/Rankine" class="mw-redirect" title="Rankine">Rankine</a> or <a href="/wiki/Kelvin" title="Kelvin">kelvins</a>, and <i>k</i> = ratio of specific heats (approximately 1.4 for air). The rise in air and temperature ratio means compression does not follow a simple pressure to volume ratio. This is less efficient, but quick. Adiabatic compression or expansion is favored by good insulation, a large gas volume, or a short time scale (i.e., a high power level). In practice there will always be a certain amount of heat flow, as to make a perfect adiabatic system would require perfect heat insulation of all parts of a machine.</li> <li><a href="/w/index.php?title=Polytropic_process&action=edit&redlink=1" class="new" title="Polytropic process (not yet started)">Polytropic</a> - This assumes that heat may enter or leave the system, and that input shaft work can appear as both increased pressure (usually useful work) and increased temperature above adiabatic (usually losses due to cycle efficiency). Cycle efficiency is then the ratio of temperature rise at theoretical 100 percent (adiabatic) vs. actual (polytropic).</li></ul> <div class="mw-heading mw-heading2"><h2 id="Staged_compression">Staged compression</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Gas_compressor&veaction=edit&section=11" title="Change section: Staged compression" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Gas_compressor&action=edit&section=11" title="Edit section's source code: Staged compression"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Since compression generates heat, the compressed gas is to be cooled between stages making the compression less adiabatic and more isothermal.
