Clapeyron charts

Some examples from this family of charts in thermodynamics with the two couples (T,S) and (P,V) include Andrew s charts (P = fiV)), Clapeyron charts PV=fiP)) and entropic charts (7 =fS) as well as deformation charts... [Pg.35]

Use the vapor composition and the Clausius/Clapeyron equation in reverse to roughly estimate AHvap. This requires two points on the vapor pressure chart. [Pg.178]

Estimate the vapor pressure of a pure substance at a specified temperature or the boiling point at a specified pressure using (a) the Antoine equation, (b) the Cox chart, (c) the Clausius-Clapeyron equation and known vapor pressures at two specified temperatures, or... [Pg.239]

Why would it be preferable to use a Cox chart to plot and extrapolate the data of question 2 rather than the Clausius-Clapeyron equation ... [Pg.246]

Estimate the vapor pressure of acetone (mm Hg) at 50 C (a) from data in Perry s Chemical Engineers Handbook and the Clausius-Clapeyron equation, (b) from the Cox chart (Figure 6.1-4), and (c) from the Antoine equation using parameters from Table R4. [Pg.282]

Prepare an Othmer chart to predict the heat of vaporization of methyl alcohol at 90°C. Use water as the reference substance. Repeat using the Clausius-Clapeyron equation. [Pg.408]

The solubility of common gases in hydrocarbon liquids is determined to meet requirements of aerospace industry. This test method is based on the Clausius-Clapeyron equation, Henry s law, and the perfect gas law. The results are important in the lubrication of gas compressors where dissolved gas may cause erosion due to cavitation. In fuels, dissolved gases may cause interruption of fuel supply and foaming in tank. The liquid density is determined experimentally. Using this density, the Ostwald coefficient is taken from a chart and used for e calculation of the Bunsen coefficient (solubility of gas). The solubility of the gas or mixture of gases and Henry s law constant are also calculated. [Pg.1066]

Vapor pressure at any given temperature can be estimated by the use of Antoine (eq. [2.3.4]) or Cox (eq. [2.3.5]) equation (or chart). Both equations are derived from Clausius-Clapeyron equation ... [Pg.50]
