Overshot Waterwheel Diagram - How It Works & Historical Significance #3580712 (License: Personal Use)

This diagram depicts an overshot waterwheel, where water is delivered via a headrace to the top of the wheel, filling buckets and using gravity to generate torque. The wheel rotates clockwise (as shown), discharging water into the tailrace below. Unlike undershot designs, overshot wheels achieve high efficiency (up to 80%) by leveraging both kinetic and potential energy of the water.
