$8-83$ Reconsider Prob. $8-82.$ 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$.$ P$8-83).$ 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, and $(c)$ the thermal efficiency of the plant.
