Bernoulli & Pressure Explorer

Bernoulli's principle states that in a flowing fluid, an increase in velocity leads to a decrease in pressure (and vice versa). It is a consequence of conservation of energy applied to fluid flow.

The Venturi effect is the drop in pressure that occurs when fluid flows through a constricted section of pipe. As the pipe narrows, the fluid speeds up (continuity equation) and pressure drops (Bernoulli's equation).

Air flows faster over the curved top surface of a wing than the flatter bottom. Faster air means lower pressure above the wing and higher pressure below, creating an upward net force (lift).
