Item Description

Study of open channel flows is a subject of interest in basic fluid mechanics and Hydraulics. A flow channel with a provision to control depth of flow over in the channel can provide a very useful tool to study several aspects of open channel flows. Adjustable Bed Flow Channel Unit is an essential equipment for fluid mechanics, hydraulics, civil, mechanical and related laboratories in science and engineering institutions.  

The Sci-tech Adjustable Bed Flow Channel Unit Model FM 32 is suitable for demonstrations and teaching of open channel flows. By closing the top of the channel, the unit can also be used to demonstrate duct flows. The complete unit is mounted on a mobile platform fixed on castor wheels. The apparatus is self sufficient with water recirculation system consisting of flow inlet tank, centrifugal pump, flow control valves, discharge tank, water flow meter and sump tank. The inlet tank consists of baffle plate and screens to reduce disturbances in the flow. The discharge tank consists of adjustable over flow weir which can be adjusted to control flow conditions in the working section. The working section is transparent and is made of clear acrylic. Other components of the unit are made of corrosion resistant materials. Experiments can be conducted in both open channel flow and duct flow modes. The channel consists of adjustable floor section which along with the transition section can be raised or lowered using suitable inserts. The combination of adjustable floor and upper boundary plate enable formation of various types of ducts to conduct experiments. Flow control valve is provided upstream of the inlet tank control flow rate. The mid-section of the upper boundary wall is made removable for fast changing and installation of models in the working section. Total pressure probes and static pressure tapings are provided at five locations along the working section. Total pressure probes can be moved vertically and fixed at different positions over the depth of the channel. Different models, such as hump, weirs etc., required to carryout studies mentioned in the list of experiments are supplied. Provision is made to fix models in the working section using suitable fixtures.
