psi =pound/square inch The force of liquid on submerged object Is perpendicular to the object’s surface Atmospheric pressure at sea level is 105 Pa. What is it in PSI?
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 Goethe barometer (water based) Mercury barometer aneroid barometer
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.
