I also created a MathCAD file that allows the user to input values for approach velocity, number of people getting water from the filter, and average volume of water consumed by one person per day. With these values, the program calculates the necessary diameter of the filter. The program looks at available diameters for purchase from various online websites and finds the closest diameter available at an equal or greater dimension. Given In addition, given the user's input of how many orifices he or she would like to drill into the bottom of the filtration unit, the file calculates the diameter of each orifice needed in order to control flow through the filter. Using this diameter and information of available drill bit sizes for purchase, the file outputs the closest drill bit diameter of equal value dimension available to buy.
After combining my and my teammates designs (inlet + body + outlet), our group hopes to finalize a design for this unit, submit a finanical financial aid proposal to EPA's P3 competition, and run experiments to determine our unit's effectiveness as a point-of-use system.
