top of this fluid are 20 cm of water with a density of 1 g/cm³. The vessel is sealed
and pressurized to a gauge pressure of 10,000 Pa. The bottom of the vessel is
square with 15 cm width.
a. [4] What is the gauge pressure (Pa) at the water and denser fluid interface.
11960 Pa
15 cm
b. [4] What is the gauge pressure (Pa) at the bottom of the vessel.
17840 Pa
c. [8] If the vessel is a square shape on the bottom, what is the net force (N) on one
wall of the vessel in the x direction on the bottom 10 cm of the wall. (assume the
vessel wall is rectangular in shape and perpendicular to the bottom for this
section of the vessel).
223.5 N
