( 4 ) The absolute pressure at the bottom of a vessel which
contains several immiscible liquids
Pabs = Delta [ P1+P2+P3 ]+ Pa = r1h1g+r2h2g+r3h3g+Pa |
|
( 5 ) All points inside still liquid lying on the same horizontal level
are under equal pressures.
This explains why no movement of liquid in the Pascal's vases .
| ( 6 ) The dam's base is made thicker than its top to overcome the high
pressure at great depth P a h . |
|
( 7 ) Average side pressure is obtained at the middle point of the
vertical side.
