About This

• This communicating vessel demonstrator is specialized fluid statics experimental equipment for verifying the core rule of static liquid pressure: when a single homogeneous liquid fills connected containers, the liquid will stay at the identical horizontal height no matter the tube shape or cross-sectional area.
• The apparatus comes with four transparent glass tubes of distinct shapes and different inner cross-sections, all linked via a shared bottom flow channel and fixed on a stable lightweight plastic base. Inject colored liquid into any tube, users can directly observe consistent liquid height across all four tubes to rule out geometric interference factors.
• The fully transparent glass structure delivers sharp liquid level visibility. A flat white panel can be placed behind the instrument during demonstration to enhance the contrast of tinted liquid, making the uniform horizontal liquid easier to identify for repeated fluid mechanics comparative tests.
• Compact overall dimension (175mm width × 168mm total height) and only 165g net weight support flexible layout on all flat experimental countertops. The rigid plastic base firmly holds all glass tubes without sliding or tipping during liquid filling and draining cycles.
• Standardized maintenance steps effectively extend service life. Rinse all glass pipelines thoroughly with clean water after each experiment to remove residual pigment stains, then store the whole set in dry, collision space to prevent glass breakage and plastic base damp deformation.
