Pascals 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
15
Buoyant forces and Archimedess 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.
