Entrance tank dimensions and elevation are a critical criteria in plant operations. All headloss throughout the plant must be accounted for in the entrance tank. Furthermore, the addition of the rapid-mix tube has added to the depth of the entrance tank. Full analysis of these parameters can be found on the Agalteca Page (***Karen, please show me how to link to this page.) **Monica- make a drawing for Agalteca headlosses in entrance tank
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

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.
Brake
Fig 1.4 Slide and Brake
The brake keeps the slide in place, also a component from 80/20 Inc. The brake naturally keeps the slide in place, while pushing on the area shown on the diagram relieves the pressure and allows for the movement of the slide

Stock Tank
The stock tank will sit on the triangular table that is pictured. The table for the stock tank was decided to be 24.13 cm (9.5 inches) tall to provide enough head to demonstrate how our system works.
Constant Head Tank
The constant head tank is maintained on this makeshift platform that will place the tank at the same level as the lever arm.As shown in our current design, most of these constraints can be met. We are using a slide mechanism that has a manual "brake" which allows the slide to be clamped in any position. (Describe how this "brake" mechanism works. Label figure below)
