Problem 2.26:
Use the SRK equation to calculate the molar volume of isobutane at the following states:
a) 30 °C, 1 bar.
b) 30 °C, 10 bar.
c) Saturated liquid at 30 °C.
d) Saturated vapor at 30 °C.
For parts c and d, compare with the saturated molar volumes reported in the NIST Web Book.
Additional information: The saturation pressure at 30 °C is 4.05 bar.
