Code:
 Exponential Change Student ID:________________ Name:________________ , ________________ |______| (last) (first) DL Sec# a)  A
large
gas
tank
is
used
to
fill
up
a
balloon
as
shown.

The
gas
tank
has
a
pressure
of
1.1
MPa
 and
the
cross
secPonal
area
of
the
pipe
leading
to
the
balloon
is
2
cm2.

Find
the
flow
speed
 out
of
the
pipe
leading
to
the
balloon
and
then
the
Current.

(Assume
there’s
no
dissipaPon)
 I b)  A
smaller
tank
is
plugged
up
to
the
larger
tank.

What
can
you
say
about
the
Current
in
comparison
to
 the
setup
in
part
a?

Describe
the
behavior
in
1
sentence
and
make
2
plots
of
[Pressure
vs.
Time]
and
 [Flow
Rate
vs.
Time]
in
the
smaller
tank.
 I c)  Biologists
oIen
use
circuit
theory
to
solve
problems.

For
example
they
use
a
circuit
to
model
the
flow
of
 ions
across
the
cellular
membrane.

Draw
an
equivalent
circuit
for
the
Large
tank
connected
to
the
 smaller
tank.
