Mechanics of FluidsSediment Flow Channel: 600mm Wide
The channel is designed for studying the sediment transport and bed forms as well as flow phenomena without sediment. It is a service unit to be used with optional accessories and models. Instruction manual is also included.
Under Frame
The channel bed rests on twin I-beam under frame which ensures static loading deflections are kept to a minimum. The length of the I-beam is about 6 m Each section is shipped with glass side walls. This simplifies site installation as there are less joints and is easier to ensure straight side walls throughout the length. To ensure minimum deflection, the I beam base frame of 18 m is supported by a fulcrum at the middle and adjustable height support at both up stream and down stream ends for a total of 3 supports. The number of supports is 5 for 30 m channel length.Slope Adjustment
Each adjustable height support uses twin screws and with a system of worm and wheel gear boxes and miter gears which are intern driven by a motor. A slope scale is provided at one end of the flume.Channel Bed
The channel bed is made of stainless steel with twin screw holes of equal distance along the channel length to hold accessories or models to the flume bed when used as a normal tilting flow channel. These holes can also be used for pressure tapping points to measure pressure loss along the channel length.Side Walls
For safety reasons, the side walls are made of tempered glass. The walls are supported at interval by brackets with screws for vertical position adjustment.Instrument Carriage
Top rails made of stainless steel tubes are attached to the top angle on each wall of the channel. Screws supporting the rails can be adjusted to ensure uniform height and in a straight line. A scale graduated in mm. is attached along the full length of one top angle of the walls. The instrument carriage is manually operated.Head Tank
The head tank is made of stainless steel and its sides and bottom are curved to ensure smooth flow into the channel. Perforated plates are also provided in the head tank to further smoothen the flow.Sediment Feeder
The channel bed may be filled by a sediment feeder with a slope stopper upstream and another one just before sediment trap at the downstream end of the channel. Feeding is by a screw.Sediment Trap
A Sediment trap is provided at the down stream end of the channel. The trapped sediment can be discharged by a bottom value. The trap is covered when used as a normal flow channel.Storage Tank
An underground concrete storage tank is recommended as standard. This tank is to be built by the user. However, above ground tank is available at additional cost.Walkway
A steel walkway with a checker plate floor and side rails is provided on one side of the flume for ease of model installation and flow observations.Circulating Pump

Strength and Property of MaterialsThin Cylinder
This equipment is used for studying the stresses in a thin wall cylinder.
A thin wall aluminum alloy cylinder is mounted on a rigid steel frame. Internal pressure is applied to the cylinder by means of a hydraulic hand pump with oil reservoir. Pressure in the cylinder is indicated on a pressure gauge. A hand wheel is attached to one end of the frame to operate a piston on one side of the cylinder. By applying the hand wheel, the piston can open or close the cylinder. When the cylinder is open, only circumferential stress occurs on the cylinder. When the cylinder is closed, both circumferential and axial stresses occur. Strain gauges are of the same gauge factor and the gauges are fixed onto the cylinder at different angles. Each strain gauge is wired to form a full bridge with temperature compensation gauge and zero adjustment in a bridge box with strain gauge indicator.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Measurement of strains and stresses under internal pressures.
- Determination of Young’s modulus a Poisson’s ratio.
