Ethane (c2h6) is burned at atmospheric pressure with a stoichiometric amount of air as the oxidizer. determine the heat rejected, in kj/kmol fuel, when the products and reactants are both at 25c, and the water vapor appears in the products as water vapor. ( 1,427,820 kj/kmol)

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.
