The correspondence between the problem set in this sixth edition versus the
problem set in the 5'th edition text. Problems that are new are marked new and
those that are only slightly altered are marked as modified (mod).
Study guide problems 2.1-2.22 and 2.23-2.26 are all new problems.

Concept-Study Guide Problems
2.1
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 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 W
T
exchanger) at state 2. A rotating shaft gives
a rate of energy (power) to the electric
generator set. 2
, Sonntag, Borgnakke and van Wylen
2.2
Make a control volume around the whole power plant in Figure 1.2 and with the help
of Fig. 1.1 list what flows of mass and energy are in or out and any storage of
energy. Make sure you know what is inside and what is outside your chosen C.V.
