Bernoulli's Principle - Obedient Ball/Suspended Ball/Circulating Ball/Fluid Mechanics - Science Museum Exhibits Scheme
What It Shows
By observing the cyclic motion of the ball under the influence of airflow, we can understand the relationship between flow velocity and pressure in the fluid.
Press the button on the booth to start the fan. The vertical upward airflow lifts the ball and moves it upwards along the center of the airflow. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Reminder: According to Bernoulli's theorem, vertical airflow creates negative pressure inside the U-shaped tube. When the ball moves to the upper port of the U-shaped tube, it obediently changes its vertical upward path under the action of negative pressure, enters the pipeline for horizontal movement, and finally returns to the starting point, completing a cycle of motion.
Science Behind It
Daniel Bernoulli proposed the Bernoulli principle in 1726. This is the fundamental principle adopted by hydrodynamics before the establishment of the continuum theory in fluid dynamics, which essentially involves the conservation of mechanical energy in fluids. Namely: kinetic energy+gravitational potential energy+compressive potential energy=constant. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. The most famous inference is that when flowing at a constant height, the flow velocity is high and the pressure is low.
