Flow Over Notches (Hb Accessory) Manufacturer,Supplier and Exporter in India

Flow Over Notches (Hb Accessory)

Product Code : SCL-CELE-14020

This equipment is designed to visually demonstrate and quantitatively measure the flow rate of water over various notches (or thin-plate weirs). It allows for the experimental determination of the coefficient of discharge (Cd) for different notch geometries using the volumetric method.

1. Key Components and Design

The apparatus uses an open channel and a precision gauge for head measurement.

  • Flow Channel (Test Section): The main body where the flow is established.
    • Size: 600 x 250 x 180 mm.
    • Material: Made of Stainless Steel.
    • Design: Features a deepened entry section to ensure smooth, uniform flow before the notch. Water is supplied from the bottom.
  • Notches (Weirs): A set of three interchangeable notches, made of Brass, is provided:
    • Rectangular Notch
    • 45 degree V Notch
    • 60 degree V Notch
  • Head Measurement:
    • Pointer Gauge: Fitted with a Vernier scale.
    • Function: Used to accurately measure the height of the fluid (head, H) above the crest of the notch.
  • Structure: The entire set-up is arranged on a rigid structure painted with industrial PU Paint.

2. Experimental Purpose

The primary objective is the calibration and verification of notch flow formulas.

  1. Head-Discharge Relationship: Determine the relationship between the measured head (H) and the actual volumetric flow rate (Q actual).
  2. Coefficient of Discharge (Cd): Calculate the Coefficient of Discharge for each of the three notch types by comparing the actual measured discharge with the theoretical discharge.
