yp = yc + Ixx,c / yc Awhere yc is the location of centroid and
Ixx,c / yc Ais the downward shift of center of pressure relative to centroid
When a fluid is in static equilibrium,
the hydrostatic pressure increases/decreases____________ with depth;
the pressure gradient (rate of change) depends on the ____________ of the fluid.
Something about manometer:
A manometer is a device which measure small pressure difference based on the difference in ____________ between fluid columns
For a given pressure difference, the difference in height between the fluid columns will be greater if a fluid of lower/higher density is used.
The pressure equation:
P2 = P1 +/- r g h
describes the pressure variation in a manometer. The minus (-) sign is used when Point 2 lies above/below Point 1 and vice versa.

If one of the sides of the fish tank is slightly sloped at 30o, how will the followings be different?
If the slope is replaced by a
What do you expect the results to be?
