This equipment is designed to study laminar flow in two dimensions. It is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied) for a water supply and flow measurement.

Two horizontal plates are placed closely together with seals on side edges.  The top plate is transparent and has a transparent grid to help observe stream line patterns.  This plate is removable to insert or remove models.  The bottom plate has small holes which are connected by valves to a water supply or source and a drain or sink.  Water is admitted through a diffuser at one end and drained at the other end. Stream lines are produced by regulating a flow of dye from a reservoir through a series of very small holes at the upstream end.  

The set rests on adjustable screw supports with bull’s eye level.

Instruction manual is also included.
