Hydrogen peroxide, H2O2, enters a gas generator at 77 F, 75 lbf/in 2 at the rate of 0.2 lb m/s and is decomposed to steam and oxygen exiting at 1500 R, 75 lbf/in 2. The resulting mixture is expanded through a turbine to atmospheric pressure, 14.7 lbf/in 2, as shown in Fig. P14.27. Determine the power output of the turbine, and the heat transfer rate in the gas generator. The enthalpy of formation of liquid H2 O2 is 80541 Btu/lb mol.
