pressure in pipes, channels etc.

atmospheric pressure

very low pressure

difference of pressure between two points

2 meters of water column

3 meters of water column

3.5 meters of water column

4 m of water column

same

higher

lower

lower/higher depending on weight of body

at the center of gravity

above the center of gravity

below be center of gravity

could be above or below e.g. depending on density of body and liquid

only when the fluid is frictionless

only when the fluid is incompressible and has zero viscosity

when there is no motion of one fluid layer relative to an adjacent layer

irrespective of the motion of one fluid layer relative to an adjacent layer
