A cylinder fitted with a piston have two stopped as shown in fig. The cylinder full with steam at 400 Kpa and 900 °C. The valve is opened allowed to the high pressure steam follow into the flat balloon (that pressure proportional with squire diameter) until the cylinder pressure reached to 200 kPa while the piston still touching stops. The balloon pressure is 300 kPa and 400°C of temperature Find: 1) Heat transfer & work done in cylinder? 2) The work done in balloon?
