The use of Chebyshev polynomials for the representation of vapour pressures between the triple point and the critical point
Abstract
Chebyshev polynomials have been used for the correlation of vapour pressure and temperature from the triple point to the critical point for two simple liquids (oxygen and methane) and also for some liquids containing more complex molecules (hydrocarbons and alcohols). Advantages of the use of Chebyshev polynomials over other vapour pressure equations are indicated.
