A78-percent-efficient steam boiler is used to generate saturated water vapor at 350°f. water enters the boiler at the steam pressure as a saturated liquid. municipal solid waste (msw) is burned at a rate of 60 lbm/min in the boiler and the heating value of msw is 9000 btu/lbm. the generated steam is run through an ideal turbine-generator unit to generate electricity. the pressure at turbine outlet is 10 psia. determine the rate of steam generation and the power output from the generator.
