Question:

Reconsider Prob. 18-91. Now, it is proposed that the liquid water coming out of the separator be routed through another flash chamber maintained at 150 kPa, and the steam produced be directed to a lower stage of the same turbine (Fig. P18-92). Both streams of steam leave the turbine at the same state of 10 kPa and 90 percent quality. Determine
(a) The temperature of steam at the outlet of the second flash chamber
(b) The power produced by the lower stage of the turbine
(c) The thermal efficiency of the plant.
