Question: In a steady-flow process, carbon dioxide gas is compressed from an initial pressure of 15 psia to a final pressure of 520 psia. The compressor

In a steady-flow process, carbon dioxide gas is compressed from an initial pressure of 15 psia to a final pressure of 520 psia. The compressor is provided with 5360 Btu/lbmol of CO2 compressed shaft work. The CO2 has a starting temperature of 50F, and the end temperature after compression must be 200F. CO2 is delivered to the compressor through a pipe with a 6 in ID and a 10 ft/s velocity. H1 = 307 Btu/lbm and V1 = 9.25 ft3/lbm were the original values. H2 = 330 Btu/lbm and V2 = 0.280 ft3/lbm at the intended final condition. Will heat be required to achieve these ultimate conditions? to be moved from CO2 or to be added to it?

Calculate the rate of heat transfer in Btu/hr. The kinetic energy and potential energy changes in the CO2 in this process may be neglected.
