Description: The channel is fitted with a PVC inlet tank, and is designed for free discharge into the Hydraulics Bench. The flume is mounted on a rigid framework, and can be tilted by use of a calibrated screw jack, which allows accurate slope adjustment of the channel. The inlet tank incorporates a stilling arrangement to diffuse the water flow prior to entry into the channel, ensuring smooth uniform flow. The level in the working section of the flume is controlled using an overshot weir at the discharge end. Bed pressure tapping’s and fixing points for models are provided. A longitudinal scale positioned at the top of the channel allows depth gauges and Pitot-static tubes to be accurately positioned along the channel length.
Specification:
1.It can carry out a number of quantitative experiments such as weir flow, hydraulic jump experiment, stilling pool energy dissipation experiment, stilling sill energy dissipation experiment, and ski-jump energy dissipation experiment.
2.It can demonstrate water flow phenomena such as thin-wall weir, bucket flow, WES weir, right-angle inlet wide-top weir, rounded inlet wide-top weir, and outflow under the gate.
3.It can measure various hydraulic parameters such as the discharge coefficient of the weir flow, the submerged coefficient, and the conjugate water depth of the hydraulic jump.
4.The parameters related to the underflow energy dissipation of underflow and ski-jump energy dissipation can be measured to verify the correctness of the design.
5.Through experiments to deepen the understanding of the factors affecting roughness, draw the relationship curve between the uniform flow depth and roughness.
