Water Dispensing System Sketch

Context

Overall Idea: 

The dispersion system will act as the source of water for the entire project. The water will be added to the basin / storage receptacle at the end of the water shed and then pumped into the basins at a constant rate. After a scenario is modelled the water will then be able to be pumped back into the system creating a circular system.

Dam: The dam is within the watershed and is used for two purposes. The first is to prevent water from leaving the watershed so that flooding conditions can be accurately simulated. The second purpose is to manually control when water is added back into the drainage bucket after a scenario is modeled.

Drainage Bucket: The will be a sloped receptacle that will receive water from the watershed when the dam is lifted. It will be sloped down and towards the watershed so that it drains into the piping system. The bucket will have a large surface area to try and minimize the head pressure of the water so that flow into the pump is consistent.

Pipe: For the pipe, it is planned to be ½ inch universal tubing so that we can use standard quick release components for all the valves and pumps. This pipe will run from the drainage bucket at the end of the watershed and then fork into both of the basins using a check valve so that backflow is prevented. The fork will be equipped with a valve that will allow flow to either basin to be blocked.

Pump:

Using the excel calculator, the minimum discharge rate was found to be 0.41625 in3/sec. Using this number an inline pump was found that is capable of 2 in3/sec. This pump will be at the corner of the pipe and will be used to pump water into the basins. This will ensure a consistent flowrate for accuracy in the scenarios.
