Steam enters a turbine at a pressure of 1000 psia and a temperature of 1100°f with a mass flow rate of 20 lbm/s, and exits at a saturated vapor at 100°f. in this process, the turbine casing transfers 400 btu/s of heat to the engine room. the exiting steam leaves the turbine at a velocity of 500 ft/s. the exhaust steam is subsequently cooled in an adiabatic condenser by cooling water which enters the condenser at 40°f and leaves at 55°f·the condensed steam leaves at 65°f at the same pressure as at the condenser inlet determine (a) the power produced by the turbine in horsepower, (b) the cross-sectional area of the turbine inlet and turbine exit in square feet, and (c) the volume flow rate of cooling water required in gallons per minute. show the two processes on a t-v diagram with respect to saturation lines.
