This problem deals with the isothermal, steady-state compression
of methanol at, 65 [°C] from its saturation pressure up to 5.0
[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.
calculate and report the following:
Density of methanol at the given temperature in [kg/m³]
Specific volume of methanol at the given temperature
in [L/kg]
Initial pressure in the compression process in [kPa]
Change of specific enthalpy in the compression
in [J/kg]
and molar enthalpy in the compression in [J/mol]
Change of specific entropy in the compression
in [J/kg·K]
