Experimental
...
Setup
...
The
...
clay
...
pot
...
is
...
placed
...
inside
...
a
...
larger
...
bucket
...
(approximate
...
volume=12L),
...
so
...
that
...
the
...
pot
...
rim
...
is
...
positioned
...
perfectly
...
on
...
the
...
rim
...
of
...
the
...
bucket.
...
The
...
large
...
bucket
...
has
...
a
...
hole
...
at
...
the
...
bottom
...
and
...
a
...
tube
...
is
...
connected
...
to
...
a
...
pressure
...
sensor.
...
The
...
tube
...
has
...
a
...
closed
...
valve
...
at
...
the
...
end
...
to
...
make
...
sure
...
no
...
water
...
empties
...
through
...
the
...
tube
...
until
...
the
...
user
...
manually
...
changes
...
the
...
valve
...
position.
...
One
...
liter
...
of
...
water
...
is
...
poured
...
into
...
the
...
large
...
bucket
...
as
...
a
...
starting
...
water
...
level
...
(or
...
zero
...
pressure)
...
before
...
any
...
experiment.
...
In
...
Process
...
Controller,
...
the
...
sensor
...
should
...
be
...
zeroed
...
at
...
the
...
start
...
of
...
the
...
experiment.
...
At
...
the
...
start
...
of
...
the
...
experiment,
...
the
...
Process
...
Controller
...
state
...
should
...
be
...
changed
...
to
...
Data
...
Collection,
...
where
...
data
...
is
...
collected
...
every
...
second.
...
We
...
will
...
use
...
7
...
L
...
as
...
the
...
limit
...
of
...
the
...
clay
...
pot
...
volume,
...
so
...
each
...
experiment
...
should
...
use
...
7
...
L
...
of
...
influent
...
solution.
...
The
...
pressure
...
sensor
...
will
...
record
...
the
...
change
...
in
...
pressure
...
(or
...
water
...
height)
...
in
...
the
...
large
...
bucket
...
over
...
time.
...
This
...
data
...
will
...
be
...
used
...
to
...
calculate
...
the
...
flow
...
rate
...
of
...
water
...
through
...
the
...
clay
...
pot
...
using
