Mechanics of FluidsTilting Flow Channel: 600mm Wide
The channel is designed for studying the hydraulic flow phenomena. 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 only two 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 supports of 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. These holes can also be used for pressure tapping to measure pressure loss along the channel length.Side Walls
For safety reasons, the side walls are made of tempered glass or clear acrylic. 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 provided in the head tank to further smoothen the flow.Storage Tank
An underground concrete storage tank is recommended as standard. This tank is to be built by the user. However, above ground storage tank is available at additional cost.Walkway
A steel walkway with a checker plate floor and side rail is provided on one side of the flume for ease of model installation and flow observations.Circulating Pump
The pump seal is mechanical. A geared butterfly valve is provided to control an accurate flow rate.Flow measurement

Flow Measurement and Flow StudyWater Hammer Apparatus
This apparatus is used to study the effects of both pipe surge and water hammer using two separate straight pipes with a constant head tank.
Pipe surge employs a clear acrylic surge shaft to demonstrate gradual velocity change, hence pressure rise and its oscillations by slow valve closing. Water hammer employs a quick closing valve and two pressure sensors-one next to the valve and another further away. Sudden rise in pressure on quick closing valve can be demonstrated on a computer (separately supplied). The equipment is to be used with Hydraulics Bench (separately supplied).
Instruction manual is also included.
