2.1
A perfectly stirred, constant-volume tank has two
input streams, both consisting of the same Liquid. The
temperature and flow rate of each of the streams can
vary with time.
(a) Derive a dynamic model that
will
describe tran-
sient operation. Make a degrees of freedom analy-
sis assuming that both Streams
1
and 2 come from
.
upstream units (i.e., their flow rates and tempera-
tures are
known
functions
of
time).
(b) Simplify your model, if possible, to one or more
