Description:
Flow Over Weirs Accessory
Using the supplied weir plates, the measurement of flow rate in open channels can be investigated. They are used together. Water is fed into a section of channel, the water then flows over the weir into the volumetric tank and back to the sump tank. A weir with a V notch (Thomson weir) and a weir with a rectangular notch are provided for the investigations. A depth gauge for the determination of the weir head is included.
