General Program Information
This program draws the slopes into the bottom of the floctank to provide access for the water to flow out of the valves when draining. Since drains must always be put in the first and last channels of the flocculator, in the event of an even number of channels, there will be two drains placed contiguously in the channels closest to the entrance tank. This code is the same for horizontal and vertical flocculators.

Technical Program Information
1) A new layer, "flocdrainslopes,"
...
is
...
created.
...
2)
...
The
...
slopes
...
are
...
iteratively
...
drawn
...
as
...
wedges
...
in
...
each
...
channel
...
from
...
the
...
channel
...
closest
...
to
...
the
...
sedimentation
...
tank
...
to
...
the
...
channel
...
closest
...
to
...
the
...
entrance
...
tank.
...
- The
...
- width
...
- of
...
- a
...
- slope
...
- is
...
- equal
...
- to
...
- the
...
- diameter
...
- of
...
- the
...
- valves,
...
- the
...
- center
...
- of
...
- which
...
- is
...
- aligned
...
- with
...
- the
...
- middle
...
- of
...
- its
...
- channel.
...
- The
...
- depth
...
- of
...
- the
...
- slope
...
- into
...
- the
...
- bottom
...
- of
...
- the
...
- floctank
...
- is
...
- half
...
- of
...
- a
...
- valve
...
- diameter,
...
- putting
...
- the
...
- center
...
- of
...
- the
...
- opening
...
- at-grade.
...
- The
...
- length
...
- of
...
- the
...
- slope
...
- is
...
- determined
...
- by
...
- setting
...
- the
...
- angle
...
- of
...
- the
...
- slope
...
- to
...
- 30
...
- degrees.
...
- If
...
- the
...
- slope
...
- is
...
- so
...
- long
...
- that
...
- it
...
- extends
...
- beyond
...
- the
...
- nearest
...
- baffle,
...
- the
...
- length
...
- is
...
- recalculated
...
- to
...
- be
...
- 5
...
- cm
...
- away
...
- from
...
- the
...
- nearest
...
- baffle.
...
3)
...
All
...
wedges
...
are
...
unioned.
...
4)
...
The
...
"floctank"
...
layer
...
is
...
thawed
...
so
...
that
...
it
...
may
...
be
...
edited.
...
5)
...
The
...
unioned
...
slopes
...
are
...
subtracted
...
in
...
a
...
single
...
command
...
from
...
the
...
floctank.
...
6)
...
The
...
"floctank"
...
and
...
"drainslopes"
...
layers
...
are
...
frozen.
