An incompressible liquid is flowing with a velocity of 1.4 m/s through a tube that sud-
denly narrows (there is no change in height)
and increases its velocity to 3.2 m/s. What
is the difference in pressure between the wide
and narrow ends of the tube?
Assume that the density of the liquid is
1065 kg/m3
Answer in units of Pa.
