Problem on steam turbine

1) A steam turbine takes in saturated steam at 300oc and outputs steam at 4 bar. When the efficiency of the turbine is 65%, Evaluate:

a.  The final composition (vapor vs. liquid) of outgoing steam.
b.  The work generated by the steam turbine
 
2) A steam turbine takes steam at 20 bar and 450oC and produces an exhaust at 2 bar, 250oc

a.  Evaluate the amount of work produced
b.  Evaluate the efficiency of the turbine
