Hydrogen peroxide, h2o2, enters a gas generator at 25 celsius, 500 kpa, at the rate of 0.1 kg/s and is decomposed to steam and oxygen exiting at 800 k, 500 kpa. the resulting mixture is expanded through a turbine to atmospheric pressure, 100 kpa. determine the power output of the turbine and the heat transfer rate in the gas generator. the enthalpy of formation of liquid h2o2 is −187 583 kj/kmol.

Steam at a pressure of 100 kpa and a quality of 50% initially fills a rigid vessel having a volume of 0.5 m^3. the steam is then heated, causing the pressure in the vessel to rise to 150 kpa. determine: i. the mass of the steam in the vessel. ii. the temperature and quality of the steam after the heating process. ii the mass of the vapour, mg and liquid, m in the vessel after the heating process. if the steam in the vessel is now further heated, what would the pressure and temperature in the vessel be when all steam has turned into saturated vapour? b. sketch the processes in part (a) and part (b) on p-v and t-v diagrams, indicating clearly the temperatures, pressures and the paths. c.
