Question
Can pressure in a fluid be increased by pushing directly on the fluid? Give an example.
✓

Answer


Yes, but it is much easier if the fluid is enclosed.
Examples : (1) The heart increases the blood pressure by pushing on the blood in an enclosed ventricle.
(2) Hydraulic brakes, lifts and cranes operate by pushing on oil in an enclosed system.
