HM 162.30 Plate Weirs Set of four Plates Show data sheet (pdf file)
Technical Description
The HM 162.30 experimental set-up includes 4 different weir plates that can each be placed on a weir carrier and then fitted to the base of the channel. The weir plates represent an aerated plate weir, a Thomson weir, a rectangular thin plate weir, and a Cipoletti weir. Apart from the aerated plate weir, all of the weirs mentioned are measuring weirs. They are used for measuring the flow rate, whilst sharp edged aerated overflow can be investigated on the plate weir. The weir plates and weir carrier are made of PVC. Tubular seals made of plastic inserted in slots on the side of the weir plates complete the experimental set-up.
Learning Objectives / Experiments
Experiments using the aerated plate weir:
Discharge on an overflow weir
Investigation of flow action on aerated and non-aerated overflow
Occurrence of separation on a sharp edged weir
Experiments using the measuring weirs:
Determination of the coefficient of overflow
Comparison of the measuring weirs
Comparison of the theoretical and actual flow rate
For exact measurement of water levels, the use of the HM 162.52 Hook and Point Gauge on the moving HM 162.59 Instrument Carriage is recommended.
