Pascal Law Apparatus, Weinholds Type Manufacturer,Supplier and Exporter
Product Code : SEL-PLE-10184
Quick Answer: Weinhold's Pascal law apparatus shows that the pressure on the bottom of a vessel depends on liquid depth, not on its shape, using a set of 4 glass vases with identical bottom openings and a counterpoised pressure disc.

About This Product
Each vase is fitted in turn and filled until the water reaches the pointer, at which point it just pushes the pressure disc open against the load in the counterpoise pan. Because the same load is needed for every vase, whatever its shape or volume, students see that only the depth of liquid and the area of the opening matter. This is often called the hydrostatic paradox.
Frequently Asked Questions
What does the Weinhold's Pascal law apparatus demonstrate?
That the pressure a liquid exerts on the base of a vessel depends on the depth of liquid, not on the vessel's shape. The 4 glass vases differ in shape and size but share identical bottom openings.
How is the liquid level kept the same for each vase?
A vertically adjustable index pointer marks the level, so each vase can be filled to the same depth.
