. Body forces are negligible.
a.
Verify that the flow is incompressible (5 points).
b.
Is the flow irrotational (5 points)?
c.
Find the acceleration of a fluid particle at x=y=2 m and t=0 in vector form (10 points).
d.
Determine the pressure gradient at x=y=2 m and t=0 in vector form (10 points).
2.
(40 points) Water flows steadily with negligible viscous effects through the pipe shown. It is
known that the 4 inch diameter section of thinwalled tubing will collapse if the pressure
within it becomes less than 1440 lb/ft
2
. Determine the max value that
