Open & Closed Flow Channel Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14166

Overview

The Hydraulic Flow Channel Demonstrator is a versatile teaching apparatus designed to study and visualize open and closed channel flow phenomena. The transparent flow channel allows direct observation of flow patterns, energy transitions, and hydraulic behavior under various conditions.

Constructed from clear acrylic and mounted on a robust floor-standing metal frame with castors, the apparatus enables both qualitative and quantitative investigations into key hydraulic principles, including the Bernoulli equation, continuity, critical depth, and hydraulic jumps.

The system features a tilting bed section that can be raised or lowered using an external actuator, even during operation, to demonstrate the effects of bed slope and critical flow conditions. Interchangeable weirs and hydraulic structures allow for multiple experimental setups, simulating real-world open channel applications such as sluice gates, sharp crested weirs, and broad crested weirs.

Key Features

Transparent acrylic flow channel for clear visualization of flow behavior.
Adjustable channel bed for slope variation and demonstration of critical depth.
Can operate as both open and closed conduit for wide experimental versatility.
Multiple interchangeable weirs (Sharp Crested, Broad Crested, Overshot, and Undershot).
Pitot tubes and static pressure tappings for head and velocity profile measurement.
Multi-tube manometer for total and static head comparison.
Robust floor-standing steel frame with mobility castors for laboratory use.
Comprehensive Operation & Maintenance Manual supplied with experimental procedures and data sheets.
