Steam enters a steady- flow turbine with a mass flow rate of 13 kg/s at 600c , 8 mpa and a negligible velocity. the steam expands in the turbine to a saturated vapor at 300kpa where 10 perecent of the steam is removed for some other use. the remainder of the steam continous to expand to the tubine exist where the pressure is 10 kpa and quality is 85 percent . if the turbine is adiabatic . determine the rate of work done by the steam during this process.

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.
