Pascals Apparatus (SMT-FM-171)

This apparatus is designed to demonstrate Pascals law by showing that the pressure in a liquid varies with depth and is independent of the shape or volume of the container. It allows students to observe that the pressure at a given depth is constant regardless of the vessels geometry, confirming a fundamental principle of fluid statics. The unit consists of a molded plastic base into which one of four interchangeable glass vessels of different shapes can be screwed. Each vessel has a flexible diaphragm at the same height, which bulges outward from beneath under hydrostatic pressure when the vessel is filled with water. The consistent deflection of the diaphragm across all vessel shapes, when filled to the same depth, visually proves that pressure is a function of depth alone. Its primary application is in fluid mechanics education for teaching the principles of hydrostatics and pressure distribution in liquids. The key benefit is the clear and intuitive visual demonstration it provides, enabling students to directly verify theoretical concepts through hands-on experimentation and understand the implications of Pascals law in engineering systems like hydraulic presses and fluid containment.
