Carbon dioxide gas enters a steady-state, steady-flow heater at 45 lbf/in.2 60 F, and exits at 40

Question:

Carbon dioxide gas enters a steady-state, steady-flow heater at 45 lbf/in.2 60 F, and exits at 40 lbf/in.2, 1800 F. It is shown in Fig. P6.63 here changes in kinetic and potential energies are negligible. Calculate the required heat transfer per lbm of carbon dioxide flowing through the heater.
