There
are
basically
two
different
distribution

configurations
:
____________________
systems
and
____________________
systems
.

.
For
residential
consumers
,
the
minimum
desirable
distribution
pressure
is
____________________
psi
.
A
pressure
over
____________________
psi
is
considered
high
.

In
fluid
dynamics
,
head
can
be
measured
by
the
____________________
to
which
water
rises
in
a
____________________

directly
open

the
water
.

.
Static
____________________
is
potential
energy
of
the
water
at

measured
in
feet
of
water
,
and
is
the
change
in

.
Static
____________________
is
pressure
of
water
at
rest
and
is
measured
in
____________________
per
square
inch
(
psi
)
.

.
Head
____________________
is
energy
loss
due
to

as
water
moves
through

distribution
system
.

To
calculate
the
head

in
straight
pipe
,
use
the
