ZM8118 HYDRAULIC FLOW DEMONSTRATOR educational lab equipment Hydrodynamics Lab Equipment
INSTRUCTIONAL CAPABILITIES
The Hydraulic Flow Demonstrator simply connects to a standardHydraulics Bench to permit the study of the following basic aspects of fluid flow:
Closed conduit flow
• Application of the Bernoulli and Continuityequations to converging and diverging flow
• Effect of gradual and sudden changesin cross section (energy losses)
• Using a contraction as a flowmeasuring device
• Using a Pitot tube to measure velocity / velocity profile
• Flow through a Culvert
Open channel flow
• Flow beneath an UndershotWeir (Sluice Gate)
• Flow over Sharp Crested, BroadCrested and Ogee WeirsUsing hydraulic structures to measure flow in an open channelEffect of changes in upstreamand downstream water level
Characteristics of Clinging, Aerated,Depressed and Drowned Nappes
• Sub-critical, Critical and Supercritical flow/ depth. Changes in
• Specific Energy and control imposedby the minimum energy condition
• Characteristics of Hydraulic Jumps
• Force and energy conditions in aHydraulic Jump
• Flow patterns associatedwith Hydraulic Jumps
• Flow over Drop Structures / EnergyDissipation
• Changes in flowprofi le in relation tothe Froude Number (predicting flow conditions in an open channel)
• Observation of flow patterns associatedwith flow around hydraulic structures
• Velocity of gravity waves in shallowwater / Formation of surfacewaves near critical depth
• Project work – Evaluation of userconstructed hydraulic structures
