Tenders Description & Specification for Hydraulic Flow Demonstrator
Hydraulic Flow Demonstrator
The Hydraulic Flow Demonstrator simply connects to a standard Hydraulics Bench to permit the study of the following basic aspects of fluid flow:
Open channel flow
Flow over Sharp Crested, Broad Crested and Ogee Weirs Using hydraulic structures to measure flow in an open channel Effect of changes in upstream and downstream water level
Flow beneath an Undershot Weir (Sluice Gate)
Closed conduit flow
Application of the Bernoulli and Continuity equations to converging and diverging flow
Using a contraction as a flow measuring device
Using a Pitot tube to measure velocity / velocity profile
Effect of gradual and sudden changes in cross section (energy losses)
Flow through a Culvert.
Characteristics of Clinging, Aerated, Depressed and Drowned Nappes
Sub-critical, Critical and Supercritical flow/ depth. Changes in
Specific Energy and control imposed by the minimum energy condition
Changes in flow profile in relation to the Froude Number (predicting flow conditions in an open channel)
Observation of flow patterns associated with flow around hydraulic structures
Characteristics of Hydraulic Jumps
Force and energy conditions in a Hydraulic Jump
Flow patterns associated with Hydraulic Jumps
Flow over Drop Structures / Energy Dissipation
Project work – Evaluation of user constructed hydraulic structures
Velocity of gravity waves in shallow water / Formation of surface waves near critical depth.
