Flow Meter Demonstration

Product Description

FLOW METER DEMONSTRATION

• Bench top open channel unit designed to conduct experiments related to open channel flows and to visualize stream line patterns over or around various objects.
• The system is consist of a clear acrylic flow channel having large width-to -depth ratio.
• Overshot and undershot weirs should be provided at the inlet and exit of the channel section.
• The channel section should have a bell mouth entry to reduce flow disturbances.
• The water flow rate can be varied using a membrane type flow control valve fixed at the exit of the flow channel.
• Water flow rate and flow velocity should be measured by the volumetric measuring tank (of the hydraulic bench).
• Water should be supplied from the supply tank consisting of glass beads to reduce flow disturbances.
• Flow patterns should be visualized using dye injection through need levalves.
• Dye injection rate can be controlled and adjusted to improve the quality of flow patterns.

Experiments:

• Study of open channel flows 
• Study of flow over weirs – over shot and under shot weirs, broad and
• narrow crested weirs.
• Familiarization with water flow visualization technique.
• Demonstration of laminar and turbulent flow.
• Study of streamline patterns around cylinders at different Reynolds numbers.
• Study of flow pattern around hump, disc, cuboid etc.
• Study of vortex shedding from cylinders and bluff bodies.
• Comparison of observed streamline patterns with theory.
