What did Noria / Bamboo Waterwheel look like?

A large vertical waterwheel, up to 20m in diameter. Bamboo tubes are evenly lashed around the rim. The lower portion of the wheel is immersed in the water flow.

How did Noria / Bamboo Waterwheel work?

Water current strikes blades on the rim → wheel rotates → bamboo tubes fill with water at the bottom → tubes reach the top and mouths face downward → water automatically pours out.

Noria / Bamboo Waterwheel

A hydraulic centrifugal water-lifting device: the kinetic energy of flowing water drives a large wheel whose rim carries bamboo tubes that automatically fill and discharge water.

Scientific Principle

Water kinetic energy conversion: kinetic energy of flowing water → rotational kinetic energy of wheel → gravitational potential energy gain of lifted water.
