Technical Description
The siphon weir is a type of solid overflow weir. The discharge area of the weir is shaped like a closed canal. As soon as the water flows over the highest point, an overhang permits automatic action of the siphon weir. In contrast to a normal overflow weir, the flow takes place within a pipe rather than free flow. The utilisation of the intake effect makes flow rates larger than those of an overflow weir possible. A ventilation valve is used to regulate the flow rate. The Plexiglas experiment is placed on the bottom of the flume and attached with bolts. The experimental set-up is fitted with seals on insertion in the flume.
Learning Objectives / Experiments
In conjunction with the HM 160, the following experiments are possible:
· Function of a siphon weir
· Flow rate and drain coefficients of a siphon weir
· Pipe flows
· Comparison of overflow and siphon weirs
· Cavitation processes on overflow and siphon weirs
Features
· Investigations on a siphon weir
