1. Observe the water flow phenomenon on the wide-crested weir, and the influence of the downstream water level on the submerged overflow of the wide-crested weir.
2. Determine the discharge coefficient m value of the non-submerged wide-crested weir.
PVC water tank length 61.8cm width 40cm height 64.8cm 1 piece
Stainless steel shutter valve 1 piece
Stainless steel depth gauge 1 piece
3. Diagram of experimental equipment
The instrument is a self-circulating water supply system, equipped with a stainless steel centrifugal water pump, which is a new national high-quality energy-saving product.
The experiment was carried out in a plexiglass tank. The total length of the sink is 300cm, the width of the tank is 10cm, and the height is 23cm. A wide crest weir is installed in the tank, the weir height P=5cm,
The crest of the weir is cm long and has a right-angle entrance.
Measure the flow rate with an orifice flowmeter, control the downstream water level with a louver-type regulating valve, and measure the water level with a moving stylus.
