10 mol/s of gas flow through a turbine. Find thechange in enthalpy that the gas experiences:A. The gas is steam, with an inlet temperature andpressure T 5 6008C and P 5 10 bar, and an outlettemperature and pressure T 5 4008C and P 5 1bar. Use the steam tables.B. The gas is steam, with the same inlet and outletconditions as in part A. Model the steam as an idealgas using the value of C *P given in Appendix D.C. The gas is nitrogen, with an inlet temperatureand pressure of T 5 300 K and P 5 10 bar, andan outlet temperature and pressure T 5 200 Kand P 5 1 bar. Use Figure 2-3.D. The gas is nitrogen with the same inlet and outletconditions as in part C. Model the nitrogenas an ideal gas using the value of C *P given inAppendix D.E. Compare the answers to parts A and B and toparts C and D. Comment on whether they are significantlydifferent from each other, and if so, why.
