2.a
Make a control volume around the turbine in the steam power plant in Fig. 1.1 and list

the flows of mass and energy that are there.
k k k k k k k k k
Solution:
We see hot high pressure steam flowing in at
k k k k k k k k
state 1 from the steam drum through a flow
k k k k k k k k k
control (not shown). The steam leaves
k k k k k k
at a lower pressure to the condenser (heat

exchanger) at state 2. A rotating shaft gives a k k k k k k k k
rate of energy (power) to the electric
