,In-Text Concept Questions
, 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.
Solution:
We see hot high pressure steam flowing in
at state 1 from the steam drum through a
flow control (not shown). The steam leaves
at a lower pressure to the condenser (heat W
T
exchanger) at state 2. A rotating shaft gives
a rate of energy (power) to the electric
generator set.
2.b
Take a control volume around your kitchen refrigerator and indicate where the
components shown in Figure 1.6 are located and show all flows of energy transfer.
