Properties of gases

Abstract

Viscosity and other fluid properties are the material preconditions for fluid lubrication. Because of the compressibility and the strong coupling between density and temperature and pressure, lubrication gases show different viscosity–pressure and viscosity–temperature relationships compared to liquids. In addition, water held in gas often leads to a condensing problem in high-pressure gas seals, which also makes characteristics of gas lubrication different from those of liquid lubrication. Essentially, it depends on the physical properties of the gas.
This chapter introduces a basic knowledge of gases related to lubrication calculation, including equations of the gas state, the relationship between viscosity, and pressure and temperature and the relationship between humidity and pressure and temperature.
