About Flow Over Weirs Apparatus

Flow Over Weirs Apparatus

Introduction of Flow over weirs apparatus

A weir is an overflow structure extending across a stream or a channel and normal to the direction of the flow. They are normally categorized by their shape as either sharp-crested or broad-crested. This laboratory experiment focuses on sharp-crested weirs only. Two different types of weirs will be introduced:
1-The V-notch weir.
2-The rectangular weir (horizontal weir with end contractions).

Objective: To Study the Discharge over different type of notches.

Specification of Flow over weirs apparatus:

Dimensions of rectangular notch: Height=82mm, width=30mm
Angle of V notch weir: 900 inclusive.
Hook and point gauge range: 0 to 150mm.
Accuracy: 0.1mm.
Overall dimension of weir plates: Height=190.5mm, Width=178mm, Thickness=4mm.

Integrated and Modular Design

This apparatus comes as a self-contained unit with its own recirculating water supply and pump, but it can also be operated with an external water source if needed. The interchangeable weir plate system and adjustable inlet valve provide exceptional flexibility, allowing for easy configuration changes for a range of fluid mechanics studies.

Precision and Safety for Laboratory Use

Designed with high durability in mind, it incorporates stainless steel, PVC, and acrylic components along with insulation and electrical overcurrent protection. Its pre-calibrated nature and accurate direct-reading scale ensure reliable results, making it suitable for both routine classroom demonstrations and advanced engineering experiments.

Visual and Practical Learning Experience

The apparatus features a transparent acrylic front observation window for unobstructed visualization of flow profiles. This, paired with the graduated collection tank and user-friendly manual controls, ensures students and users can fully engage with fundamental fluid mechanics concepts through hands-on learning.

FAQs of Flow Over Weirs Apparatus:

Q: How is the Flow Over Weirs Apparatus typically used in educational settings?

A: This apparatus is primarily used in fluid mechanics laboratories for demonstrating the principles of flow measurement and for experimentally determining discharge coefficients for various weir types. Students and researchers can observe real-time water flow profiles and collect data for calculations.

Q: What types of weirs can be tested with this apparatus?

A: The equipment includes interchangeable plates for rectangular sharp-crested, triangular (V-notch), and broad-crested weirs, facilitating comparative studies of flow characteristics and efficiency for different weir geometries.

Q: When should the collection tank be drained, and how is it done?

A: The collection tank (25L capacity) should be drained when it reaches either its volumetric measurement limit or at the end of an experiment. The integrated quick drain valve allows for fast and convenient emptying of water with minimal manual intervention.

Q: Where can this apparatus be deployed for practical use?

A: It is suitable for educational institutions such as engineering colleges, university laboratories, training centers, and research environments, owing to its robust construction, portability, and user-friendly design.

Q: What is the process of adjusting the flow for experimental runs?

A: The apparatus features an adjustable inlet valve, allowing precise regulation of water flow rate. Flow is easily monitored using the direct-reading level scale and observation window to set desired experimental parameters efficiently.

Q: How does the level indicator improve experiment accuracy?

A: The built-in pointer gauge or scale provides clear, real-time indication of water surface levels, which aids in accurate volumetric measurements and ensures consistency across different experiments, minimizing reading errors.

Q: What benefits does the observation window provide during flow measurement studies?

A: The transparent acrylic front offers direct visualization of water movement over the weirs, enabling users to qualitatively study flow regimes, identify disturbances, and enhance conceptual understanding during practical sessions.
