Determine the atmospheric pressure acting on an open manometer if the height of the column is 1.75 in Hg and the pressure inside the gas is 21 psi. Pgas h = 1.75 6. Determine the total pressure (in psi) at the bottom of a 0.85-m cylinder if it is filled by water % of the way. The cylinder is not covered. 5.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
How to answer this? Thanks so much.

For 5. In Hg is a unit of pressure (specifically, pressure head (pressure due to height)). For this problem please treat it as inch (height) and Hg as the fluid being used.
