Discharge Over Notches Manufacturer,Supplier and Exporter in India

Discharge Over Notches

Product Code : SCL-CELE-13994

This equipment is a self-contained water recirculating unit designed to demonstrate the measurement of water flow rate using various notches (or weirs). It allows students to experimentally determine the coefficient of discharge ($C_d$) for different notch geometries.

1. Key Components and Design

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

  • Flow Channel: The channel has sufficient length and width where water is supplied from the bottom.
    • Test Section Size: 600 x 250 x 180 mm.
    • An arrangement for fixing interchangeable notches is provided at one end of the channel.
  • Notches (Weirs): A set of three interchangeable notches, made of Brass, is provided:
    • Rectangular Notch
    • 60° V Notch
    • 45° V Notch
  • Head Measurement: Pointer Gauge fitted with a Vernier scale. This is used to accurately measure the height of the fluid (head, $H$) above the crest of the notch in the flow channel.

2. Water Circulation and Measurement

The system includes a closed-loop water circulation and volumetric flow rate determination.

  • Water Circulation:
    • FHP Pump (Crompton make) is used to supply water from the sump tank to the channel.
    • Sump Tank: 50 Liters capacity.
  • Flow Rate Measurement: Achieved using a Measuring Tank with a Piezometer.
    • Capacity: 25 Liters.
    • An Electronic Stop Watch is provided to measure the time taken to collect a known volume, calculating the actual discharge ($Q_{actual}$).
  • Control Panel: Includes standard On/Off Switch and Mains Indicator.
