Consider the combustion of hydrogen (h2) with oxygen (o2) in a steady flow reactor as shown in the sketch. the heat loss through the reactor walls per unit mass flow (q/m) is 187 kj/kg. the equivalence ratio is 0.5 and the pressure is 5 atm. for a zero-kelvin reference state, approximate enthalpies-of-formation are h2(0)= (0) = 0 kj/mol, h20(0)=-238,000kj/mol, oh(0)=-38,600 kj/mol. a determine the mean molecular weight of the combustion product gases in the outlet stream, assuming no dissociation. for the same assumption as in part a, determine the mass fractions of the species in the outlet stream. determine the temperature in the product stream at the reactor outlet, again assuming no dissociation. furthermore, assume that all species have the same constant molar specific heats, c equal to 40 kj/kmol-k. the h2 enters at 300 k and the 02 at 800 k. now assume that dissociation occurs, but that the only minor produce is oh. write out all of the equations necessary to calculate the out-temperature. list the unknowns in your equation set.

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
