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.
