FLOW CHANNEL equipment allows the student to study water flow in an open channel and also verify the Chézy equation and Manning’s friction factor.
It is designed for use with Hydraulics Bench fitted with auxiliary pump unit, but can be used as a stand-alone unit when connected to a suitable water supply and drain. The apparatus consists of an open channel of rectangular cross section supported at each end by frames, one of which is adjustable so that the slope of the channel may be varied. The channel walls are made from clear acrylic plastic so that full visibility of the flow characteristics can be achieved. This flow channel provides a low cost experiment with accuracy comparable with larger scale channel investigations.
