1.a
Make a control volume around the turbine in the steam power plant in Fig. 1.2 and
list the flows of mass and energy that are there.
Solution:
We see hot high pressure steam flowing in 1
at state 1 from the steam drum through a
flow control (not shown). The steam leaves
at a lower pressure to the condenser (heat WT
exchanger) at state 2. A rotating shaft gives
a rate of energy (power) to the electric
generator set. 2
