  13. FCD Performance

  14. Clogging Experiment • Process Controller used to meter water into 10 cm tube. Refilled after head dropped by 40 cm. • Interested in flow rate changes for each 40 cm head drop as well as over several days.

  15. Clogging Data

  16. What We Learned • Low flow presents lots of problems • Complex and simple designs often do the same job • It is easy to overlook valuable solutions • A simple device can have vast implications in the developing world

  17. Further Research • Is there a manufactured device like this already out there? Cost comparison • Cleaning mechanisms • Manufacturing Costs and Opportunities • Material Selection • Maximum head capabilities - Sizing

  18. Steve Achieves Inner Constant Flow
