Application:_..

The Pascal's Law apparatus is used to demonstrate the hydrostatic paradox and allows for quantitative measurements of bottom pressure depending on the height of the liquid column.

Product Information:_..

The measurement system, Pascal's Law apparatus, consists of a metal base plate with a mounting bracket for an acrylic glass spout (with sealing rings and a rubber membrane) to hold the glass vessels. The liquid in the glass vessel exerts a force on the rubber membrane. The force is transmitted via a plunger from the membrane to the short lever arm of a two-arm lever. The force is magnified and displayed on a height-adjustable scale. A slot weight that can be moved along the long lever arm compensates for the force acting on the short lever arm.₁
Four differently shaped glass vessels with the same base area and height are available for experiments. A level indicator can be used to mark the fill height of the glass vessels.₁
A drain pipe at the back of the acrylic spout allows a hose to be connected for draining the liquid.
