Abstract:
The Summer 2010 Chemical Dose Controller (CDC) Team has spent the summer exploring the challenges associated with manufacturing precise orifices. The team has run a series of tests measuring flow rate on orifices created from Legris polyamide, flare cap fittings, refrigerator caps, and carburetor jets to determine their precision and accuracy. The orifices manufactured from polyamide were deemed inadequate, which caused the team to consider in- house and off-the-shelf manufactured orifices created from brass, which showed much lower deviations from the expected flow rate. This report describes the results of the team's experiments on four different types of orifices and endeavors to set future goals for next semester's CDC Team.
