Fast Water Is Cheap Water

You'll learnhow continuity and Bernoulli link speed, area, and pressure in a flowing fluid.

A thumb over the hose, a river squeezed into a gorge, a strip of paper lifting on a breath — two laws run all of it, and one of them says the opposite of what your hands believe. The last stop of the course.

FLOW LAB

Before you start

What you're looking at

A pipe narrowing to half its area, with dots drifting through it and pressure chips at each section.

The question

Why does a stream speed up where the pipe narrows — and drop to lower pressure?

Watch for

Dots crossing the narrowing; separate readouts for speed, area, pressure, and height.

What the symbols mean

A₁ and A₂ are the pipe's cross-section areas; moving dots show flow; pressure chips read each section.
