Generalized Compressibility Charts

Correlations and charts that take advantage of corresponding states to provide data for many gases are called quot; generalized quot;. Thus, a quot; generalized compressibility factor chart quot; can be used to get z once we have the reduced temperature and pressure. The are typically several different views of the chart , depending on the pressure range.

A compressibility chart for each species would be required to find the compressibility factor if the critical temperature and pressure were not converted to a generalized reduced temperature and pressure. (T/F)

By curve fitting, all the data compressibility chart is obtained. In which Compressibility factor Z is on the y-axis and Reduced pressure P R is on the x-axis. The observation made from the generalized compressibility chart is that at very low-pressure gasses behave as an ideal gas regardless of the temperature.

There is another chart that expands the region for reduced pressures between 0 and 1. Finally, there is the high pressure chart for reduced pressures between 0 and 40. Remember that the reduced properties, like reduced pressure, are dimensionless. OK, flip the page and we’ll take a look at one of the generalized compressibility charts .
