Use the following information to answer
questions 33-35:
In a chemistry laboratory it is often useful to
create a partial vacuum. A simple way to do this
involves connecting a wide pipe to a narrow pipe
which is connected to a reservoir of water (just
the water line). The reservoir has pressure
greater than the ambient atmospheric pressure,
but once flow is established, the pressure in the
narrow tube is less than atmospheric pressure. A
valve can be placed in the narrow tube to take
advantage of the partial vacuum. Assume that
there is no viscosity and that gravity plays no
role. Use the following notation:
p=density of water
Pair density of air
=
Pres pressure of the reservoir
=
P = atmospheric pressure
A₁
atm
= cross-sectional area of the narrow tube
A₂ = cross-sectional area of the wide tube
V₁ = velocity of water in the narrow tube
V2 velocity of water in the wide tube

TUBULAR TALLY
The Perseverance Mars rover is
designed to collect rock samples that
will eventually be brought to Earth for
further study. This would be the first
time we've ever brought back
samples from Mars!
After scientists identify an interesting
rock they would like the rover to
collect, Perseverance uses a special
coring bit to drill out a rock cylinder
13 mm in diameter. As the rover
drills, the rock core moves into one
of 38 available tubes that will store
the rock sample - sealed until it is
opened one day in a lab on Earth.
If the coring bit collects a rock
cylinder 60 mm in length, what is the
volume of the rock in the sample
tube?
