EXPERIMENTAL FLOWEXPERIMENTAL FLOW

Experimental velocities ranged from Experimental velocities ranged from

approximately ~3cm/s to ~20cm/s.approximately ~3cm/s to ~20cm/s.

The flow has nice continuous motion with no strong eddy currents disrupting the dye streamers

Good velocity profile showing nice orientation and the minimal frictional effects of circular geometries.
