🌊 Fluids — pressure grows with depth, and drives the jet

A tank of liquid: the deeper you go the harder the fluid pushes (P = P₀ + ρgh), and a hole low in the wall lets that pressure fling a jet out at v = √(2gh). Change the fill height and watch both respond together.

Walkthrough 1 / 3

A tank holds a liquid; the deeper you go, the harder it pushes — see the arrows.

Liquid height H 4.0 m

P_bottom = P₀ + ρgH = — kPa · jet speed v = √(2gh) = — m/s
deeper liquid → more pressure → a faster jet
