RUN 1 - 30 Jun 2003 -------------------- --------------------- Flow rate --------- 2:28:15 to fill 10.45L (lowest pump setting) Description ----------- Regular bi-directional flow. No overflowing cups. One cup always empty. Response to perturbations ------------------------- Giving the wheel a push: returns back to one cup empty state (same cup remains empty). Filling a marked cup and draining the others: the marked cup becomes the empty cup and this was insenstive to slight changes in initial conditions. Measurements ------------ No video footage of this run. Two sets of stopwatch data (labelled a and b). RUN 2 - 30 Jun 2003 -------------------- -------------------- Flow rate --------- 1:48:46 to fill 10.45L (pump setting on pen width away from lowest setting) Description ----------- Started the run by filling the marked cup and rolling the wheel anti-clockwise. Regular bi-directional with one empty cup. One cup occasionally overflows. The position of the empty cup changed (moved anticlockwise) during the first ~1/2 hour of the run (period of ~8 minutes) but then seemed to settle. A big transient?
