Book Description

Excerpt from Compressed Air: Its Production, Uses, and Applications To limit the consideration of the properties of air when sim ply compressed above the ordinary pressure of the atmosphere was believed to be wanting in scope to make the treatment of the subject complete; this work includes, therefore, a consider ation of the properties of air below atmospheric pressure, for the reason that we are surrounded by an atmosphere compressed by gravity, but it is used in the arts in many ways much below atmospheric pressure, even approaching the zero condition of a vacuum, so that, remote as the connection appears, this subject of partial pressures below the atmosphere properly belongs to a treatise on compressed air.
