Additionaly, the the frame work includes a table to hold a small stock tank and another table to hold the constant-flow device. As determined in the design of the constant head device, there should be ideally 30 cm between the orifice and the low water lever of the stock tank. This dimension has been taken into account in our design. **Find and link this page

Lever Arm
The lever arm is a 1" x 1" aluminum bar classified by the 80/20 Inc. as 1010. The length of the lever arm was decided to be 0.80 meters to account for the variation in the water level of the entrance tank from the overall head loss in the plant. The lever arm is attached on the top with components from McMaster Carr. The bar is attached to the lever arm with a clamp, while the sides of the bar are attached by bearings so that it can rotate. The lever is positioned in a way so that the slide can slide to zero and have a manual shutoff.
Slide
The slide is a component from 80/20 Inc. (Part # 6730) that we attach the orifices to. There is also a hand brake that is attached.
