"PSS" Meeting Minutes

Spring 2009 Minutes

"5/1/09"

Accomplishments

• Cut tubes and continued to run experiments holding capture velocity constant.

Issues

• N/A

Metrics

• Identified optimum capture velocity from experiments run this far. Calculated necessary tube length to hold this capture velocity constant for all diameter tubes.
• Calculated Reynolds numbers to confirm that flow in tube settlers is laminar.
• Met with Monroe and discussed additional quantitative modeling of floc sliding down/rolling up tube. From this conversation, determined velocity gradient for all tubes tested to this point, and identified correlation between velocity gradient and failure.

Outcomes

• Need to update wiki before final.
• Need to finish gathering and analyzing data.

Any Overall Team Comments: SLOPE DAY '09.
