An insulated piston cylinder device contains 0.01 m3 of steam at 200c. the force on the piston is such that it maintains a constant pressure of 400kpa inside. a valve is then opened and steam at 1mpa and 200c is allowed to enter the cylinder until the volume inside increases to 0.04m3. determine (a)the final temperature of the steam, (b)the amount of mass transfer ans: 188c, 0.018kg #10. an adiabatic air compressor is to be powered by a direct-coupled adiabatic steam turbine that is also driving a generator. steam enters the turbine at 12.5mpa and 500c at a rate of 25kg/s and exits at 10kpa and a quality of 0.92. air enters the compressor at 98kpa and 295k at a rate of 10kg/s and exits at impa and 620k. determine the net power delivered to the generator by the turbine. ans: 20,448kw 12.5 mpa 500°c 1 mpa 620 k vapor steam turbine air comp liquid steam 198 kpa 295 k 10 kpa figure for #2 figure for #7 figure for #9. figure for #10
