Exit Channel Design Program

The purpose of this program is to design the exit channel and weir that will keep a constant water level throughout the plant, which in turn will optimize the operation of the plant, as well as facilitating the monitoring of the plant.

Algorithm

This component must maintain some dimensional consistency with the other components of the plant. It consists of having inlet pipes that connect to each sedimentation tank, and a circular weir in the center that will transport the water to the storage tank. It is in the weir where water will be chlorinated.
The height of the leveling tank's wall will be the same as the height, measured from the platform of the plant, as the wall for the channel and the sedimentation tank, which is 70 cm.
The water level in the PLT is the difference between the water level in the channel and the total head loss through the launders:

An estimate of the weir diameter is obtained from the weir equation:

The height of the weir is obtained after the nominal pipe size is determined from the pipe database, and the actual height difference between the weir and the water level is subtracted from the water level measured from the bottom of the leveling tank.
The width of the plant leveling tank will have as an aesthetic reference the diameter of the chlorine tank and is calculated as the difference between the diameter of the chlorine tank and the weir diameter plus the launder diameter. The length of the plant must fit the launders and should provide space for concrete, therefore it is calculated as the sum of the diameter of the three launders, the weir diameter, and the assumed concrete space of 0.5 m:
