The force of liquid on submerged object
Is perpendicular to the object’s surface psi = p ound/ s quare i nch
Atmospheric pressure at sea level is 10 5 Pa. What is it in PSI?

Is pressure on these two divers different?

Pascal’s principle:
Change in pressure applied to an enclosed fluid is transmitted undiminished
To every point of fluid in the container.

Pressure measurements:
-open-tube manometer
-barometer aneroid barometer
Mercury barometer
Goethe barometer
(water based)

Buoyant forces and Archimedes’s principle
An object completely or partially submerged in a fluid is buoyed up by a force with magnitude equal to the weight of the fluid dispersed by the object .
