The flow channel consists of an inlet tank with overflow and flow stilling arrangement, a rectangular working section and a discharge tank. Control valves and adjustable weirs allow the flow conditions to be varied independently at the entry to and exit from the working section. The working section can be flooded to create a closed conduit or operate partially filled as an open channel. The most important feature of this equipment is the adjustable section of the bed which, together with its transition section (ramps), may be raised and lowered using an external actuator while the water is still flowing. This facility affords a striking demonstration of the significance of channel critical depth. It is also used to vary the cross section for demonstration of the Bernoulli equation in closed conduit flow. A removable panel in the roof of the working section allows models of typical hydraulic structures to be installed, namely; a Sharp crested weir, Broad crested weir. Pitot tubes and tappings connected to a multi-tube manometer allow Total and Static heads to be measured and compared at three locations in the working section. The height of the Pitot tubes is adjustable allowing the velocity profile to be determined at any position between the bed and the roof of the working section. Transparent scales allow all important heights and levels to be measured throughout the working section.

Detailed Operation & Maintenance Manual is provided along with the trainer.
