Liquid carbon dioxide (100 ft³/s) with 600 Btu/lbm enthalpy feeds through a 4.5-inch diameter pipeline to a turbine and then through a heater where 3.5 x 106 W is transferred to it. The carbon dioxide then exits through a 9-inch diameter pipeline 150 feet above the inlet. If the work input to the turbine is 2.5 x 105 Btu/s, what is the enthalpy (Btu/lbm) of the exiting carbon dioxide? Assume the density of LCO2 is 1.98g/L.
