ABSTRACT
This chapter discusses the matters in a quick review of basic theory, and most subjects will be reinforced with examples and the solutions. In all cases the practical aspects of each example are reviewed, and the necessary practical formulas are given with explanations. The pressure at which vaporization takes place and at which the vapor completely fills the space over the vaporizing liquid is the vapor pressure at the existing temperature. The temperature at which the equilibrium vapor pressure of the liquid is equal to the existing partial pressure of the vapor is the dew point. solution Pressures are so low that the vapor-gas mixture may be considered to be following the perfect gas law. The vapor content of a saturated gas is determined by the vapor pressure of the liquid and may be predicted directly from vapor pressure data which, for water, can be found in the steam tables.
