Code Number: 2B20.15

Demo Title: Pressure Dependent on Depth

Condition: Excellent

Principle: Pressure Dependence

Area of Study: Fluids

Equipment: 

PVC diaphragm app., Plexiglas box filled with water, Manometer.

Procedure: 
Attach the PVC diaphragm apparatus to the manometer.  Care should be taken not to move the diaphragm up and down in the water too fast or the manometer liquid may develop bubbles that will take time to settle out.
