You are interning at a power-plant engineering company that is in the process of designing a new steam cycle. your manager asks you to in estimating the turbine work output for 2 different operating conditions: (i) water enters the turbine at 600 °c and 17.5 mpa and exits at 20 kpa as a saturated mixture with a quality of 0.95. (ii) same inlet conditions as (i), but exits at 20 kpa as a saturated mixture with a quality of 0.85. (a) calculate the turbine work output per unit mass of water for conditions (i) and (ii). (b) comment on the difference in the turbine work output between conditions (i) and (ii). (c) show the process across the turbine for conditions (i) and (ii) on the same t–v diagram.
