  • overshot water wheel The Elements Unearthed

    Along the mill race, headgates allowed the water to be diverted onto overshot waterwheels and later onto water turbines (shown here) to run two rolling mills each. Huge metal wheels rolled around in a trough, where the correct mixture of ingredients had been placed, until they were ground to a fine powder and thoroughly mixed.

    The other thing to keep in mind is that an overshot water wheel will provide better efficiency than an undershot, providing more bang for your flow but this does limit wheel size in some situations. I think a breast-shot wheel is somewhere in between for efficiency.

    Overshot water wheels. In an overshot water wheel, the mill race brings the water to the top of the wheel, where it strikes the paddles or buckets and turns the wheel. This is more efficient because as well as the force of the flowing water, the weight of the falling water helps to turn the wheel. This is a benefit of this design as it will

    Using 12 paddles makes it easy to mark out the location of each paddle on the wheel since they are separated by a 30 degree angle (= 360 degrees / 12). The paddles were chamfered to minimise the surface area of water hit by the wheel as it rotates, with the aim of making the waterwheel as quiet as possible in operation.

    Major historical developments in the design of water

    The overshot water wheel design rst appeared during the Middle Ages. In an overshot water wheel, the weight of the water lling the buckets causes the wheel to rotate, producing power from the change in potential energy of falling water (see Figure 1(b)). One major advantage of overshot water wheels is that they are able to utilize the complete
