Additional Info
ID Code:
F4-11
Purpose:
Demonstrate laminar and turbulent flow.
Description:
Place the streamers near the front of the fan, and notice that they line up due to the laminar flow. Then place the streamers behind the fan or about one meter away, and note that they move irregularly due to the turbulent flow.
Availability:
Available
