Question

Carbon dioxide (CO2) is initially at 11.09 MPa, 3300K and then is compressed to 430°K and 22.17 MPa. a Treating carbon dioxide as an ideal gas: Find the change in specific volume between the initial & final states Find the change in enthalpy between the initial & final states per kmol Find the change in entropy between the initial & final states per kmol b Treating carbon dioxide as a real gas: Use the generalized charts to determine the change in specific volume, and the change in enthalpy and entropy per kmol. Show your factors on the appropriate charts (3 charts)

Answer 1

Ideal gas - Cos lloa mpa. 430K lempiressing 330 K., 20.17 Molla CO2 Co2 RT va PI a) Specific volume = change in In spenfic Volume = RTI Pi RT2 P2 Ti P 포 Pe :) 430 8.314 r 330 1 ) 4.4x109 11.09 22.17 119547 8xrom 3 kg 3 1095778 X10 reg to change in specific volume Ans z 1995 778 x103 m3 (cg

Change in specific volume will decrease in nature ,kita will equal to 1.95778 *10^(-3) m^3 /Kg
