Unformatted text preview: 1 • 2 • v = 8.0 m/s Physics 7B-B Quiz # 1 DL sec: Name: 1/16/08 last, frst Codes: grading use only 1 • 2 • v = 8.0 m/s 1.)
A
horizontal
pipe
is
connected
to
a
larger
pipe
with
twice
the
cross
sectional
area
as
shown.

 Treat
the
fluid
flowing
in
the
pipe
as
incompressible
and
any
dissipation
can
be
ignored.

The
 initial
speed
of
the
flow
at
point
(1)
is
8.0
m/s. ® fluid 
=
900
kg/m 3 a)

(50%)
What
can
you
determine
about
the
 speed
of
the
flow
at
point
(2)? Because
mass
is
conserved
for
the
incompressible
fluid
the
volumetric
flow
rates
must
be
equal
 at
points
(1)
and
(2). dV dt = vA 

õ

 v 1 A 1 = v 2 A 2 . We
are
given

 A 2 = 2 A 1 






õ

 v 1 A 1 = v 2 2 A 1 , Solving:

 v 2 = 1 2 v 1 
=
4.0
m/s....
