I wonder whether the viscosity of fluids scale reasonably? It's easy to
imagine that the losses involved in forcing hydraulic oil through a tube
with only one or two millimeter cross-sections would be huge compared to
the real-world device.
I suspect that pneumatics at Lego scale would operate more nearly like
hydraulics at 'real world' scales.

| I don't think that pressure shares the same fluid dynamics as liquids. Certainly on the larger scale, fluid works much better at evenly distributing pressure even though pnuematic systems are capable of very strong movements indeed. The viscosity of (...)
