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 level gauge HM 162.52 on the movable instrument carriage HM 162.59 is recommended. |
