Isothermal Properties for Isobutane

This option will supply data on a constant temperature curve over the specified pressure range. Values should not extend extend outside the minimum and maximum values given. Calculations are limited to a maxium of 601 data points; increments resulting in a larger number of points will be adjusted upward to limit the number of points computed.

  1. Enter temperature in selected units:
    (Acceptable range: -159.42 to 301.9 C)
  2. Enter pressure range and increment in selected units:
    * The maximum pressure limit is the lowest of the following values:
    • 1973.847 atm
    • The pressure at which a density of 12.74 mol/l is reached.
