Question
An air tube is open at both ends and contains constriction connected on both sides by a channel
of mercury.
a. What do you know about the air speed of the air flowing through the tube at this instant?
b. At time t later, the air speed is known to flow through the tube
from left to right at a rate of 1200 cm³/s. Draw three air
streamlines through the tube. Interpret what these lines are
telling you about the fluid moving through the tube.
c. What is the air speed in the wide and narrow parts of the tube?
d. What is the height difference in the columns of mercury? And
which column is higher?
3.0 cm
1.0 cm
