Sulfur hexafluoride - Wikipedia

It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air (1.225 g/L). It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion (ppt) in year 2019, rising at 0.35 ppt/year.Get price

Municipalities of the Netherlands - Wikipedia

The Netherlands is a decentralized unitary state, which means that the central government is supreme and delegates certain tasks to lower levels of government by law. The different levels do, however, make work agreements, which give municipalities a certain degree of independence in their policy decisions.Get price

A3.32-CIRED - Final Report-Compressed | Electrical Substation

Since the velocity of sound in oxygen is similar to that in nitrogen the results are applicable for an Sulfr hexafluoride/air mixture. The accuracy of such devices is +/-1 % Sulfr hexafluoride content. The same Condensation technique employed by a chilled mirror to measure the water vapour in Sulfr hexafluoride can be used to determine the purity of the Sulfr hexafluoride gas.Get price
