Situation This Problem Deals With The Isothermal Steady State Compression Of Methanol At 55 C From Its Saturation 1 (35.68 KiB) Viewed 54 times

Situation: This problem deals with the isothermal, steady-state compression of methanol at, 55 [°C] from its saturation pressure up to 7.0 [bar]. For liquid methanol, the density as a function of temperature, and the volume expansivity are, respectively: P = 1059.8 -0.915.T and B = 1.49x10-3K-1 Antoine constants and molar mass for methanol can be found in Appendix B, Table B.1, p. 651 of the textbook. Requirements: Please, calculate and report the following: 1. Density of methanol at the given temperature: [kg/m3] (4 pts.) 2. Specific volume of methanol at the given temperature: [L/kg] (3 pts.) 3. Initial pressure in the compression process: [kPa] (5 pts.) 4. Change of specific enthalpy in the compression: [J/kg] (4 pts.) ... and molar enthalpy in the compression: [J/mol] (3 pts.) 5. Change of specific entropy in the compression: [J/kg.K] (4 pts.) ... and molar entropy in the compression: [J/mol-K] (3 pts.)
