This problem deals with the isothermal, steady-state compression
of methanol at, 25 [°C] from its saturation pressure up to 13.0
[bar]. For liquid methanol, the density as a function of
temperature, and the volume expansivity are, respectively:
ρ = 1059.8 – 0.915·T and
β = 1.49×10–3 K–1
Antoine constants and molar mass for methanol can be found in
Appendix B, Table B.1, p. 651 of the textbook.
