Consider a stoichiometric mixture of H and O at standard condition (298.15 K and 1.05 x 105 Pa,) at the upstream. The specific heat ratio of the mixture is 1.4. The heat of combustion for this stoichiometric mixture qe is 190.5 kJ/mole. The universal gas constant R =8. 314 J/mole/ K. (1) calculate the average molecular weight of the mixture MW, the local sound speed au, the density pu (2) if the upstream flow velocity u 1 m/s, plot the Rayleigh lines, and the Hugoniot hyperboles with its asymptotes. (3) if the upstream flow velocity 2000 m/s, what is the downstream detonation pressure po, and density po
