Pipeworks

A source feeds a junction that splits to two outlets, each with its own pressure and flow-rate demand. Set each branch's bore diameter and outlet B's valve; the engine re-solves the network on every change. Narrowing a bore speeds the flow but drops its pressure, so you balance the competing outlets until both demands are met.

• Continuity: a narrower bore speeds the same flow up
• Bernoulli: faster flow means lower pressure
• Win when both outlets meet their pressure and rate

• Desktop: drag the bore and valve knobs to re-solve the plant live
• Phone & tablet: drag the knobs with your finger, fully touch-friendly

• Daily: one shared plant each day
• Practice: endless new layouts

• If an outlet needs more pressure, widen its bore rather than choking the other
• Use the valve to trim outlet B once the bores are roughly right
• Make small adjustments, the network reacts to every change at once

Pipeworks is a fluid-dynamics puzzle built on real continuity and Bernoulli relationships, teaching how fluids move through a network.

• Skills: fluid dynamics, continuity, Bernoulli's principle, flow and pressure
• Best for: roughly grades 9–12 (ages 14+)
• For parents & teachers: fluid flow you can route and reason about.

Setting bore diameters and a valve so two outlets each meet their own pressure and flow demand is network hydraulics, governed by the Hagen–Poiseuille relation.

Having the engine re-solve the whole network after every change is the original feedback.

Re-solving is necessary because the branches are coupled. Flow resistance depends on the fourth power of the bore, so a small widening dumps a disproportionate share of the flow into that branch and starves the other — which is why these systems cannot be tuned one outlet at a time.
