That's why expressing composition as volume percentages works. Wow, this is very easy to understand. If I say, I have 5 dm^3 of air in the container with the pressure of 3 atm. Let's say oxygen is 20 percent by volume in the air. First, I have to have (20/100)*5 = 1 dm^...
A set volume of air was aspirated into a saline-filled syringe and then compressed and maintained at various percentages while pressure was measured. The ... CHT Ban,LXY Li,JJ Pillay - Canadian journal of anaesthesia = Journal canadien d'anesthésie 被引量: 38发表: 2006年 Conversion of spi...
in all the settings analyzed r was systematically larger than (or close to) unity, thereby indicating that the contribution provided by the steps to the total gas evasion from the Valfredda creek was at least 50%, with even higher percentages in correspondence of low-flow and high-flow condit...
In aviation: for the blanketing and inerting of fuel tanks, mobile Nitrogen systems for the ground crew. In the storage of perishable products: for example the storage of fruit at ultra low oxygen percentages (ULO). Sign in to download full-size image Hollow fibre gas permeator for N2 gener...
space heating and water heating. In the U.S., 46% of homes use natural gas as theirmain source of heat, 40% use electricity, 10% use other fuels such as heating oil or propane, and 4% are unheated. For water heating, the percentages are 47% gas, 47% electricity and 6% other ...
The share of different processes in China’s lead and zinc production is sourced from the International Lead and Zinc Study Group24. The emission factors are weighted according to their percentages. The emission factor of magnesium includes CO2 emission from electrolysis of magnesium chloride solution...
The common occurrence of small percentages of nitrogen and carbon dioxide, in part, is considered in the correlations previously cited. Concentrations of up to 5% of these nonhydrocarbon components do not seriously affect accuracy. Errors in compressibility factor calculations as large as 10% may oc...

In subject area:Engineering Exhaust gas recirculation (EGR) is a process in which a part of the exhaust gases reuse with the intake air stream and thus dilute inlet air, lower the oxygen by volume, decrease the combustion temperature and thus significantly reduce the NOx emissions. ...
Overall, there were no significant differences among the stunning gas treatments in the percentages of hens stunned. Hens in the 30% CO 2-in-air treatment entered the lower chamber at almost the same frequency as in the Ar treatment. Most hens became stunned in the corridor when exposed to ...
