Mechanics of FluidsSediment Bed and Flow Visualization Tank
The equipment is a self-contained unit designed to study the mobile bed formation and two-dimensional flow observation.
The tank is made of stainless steel and consists of five sections.
- Head tank with perforated plate to minimize turbulence and smoothen the flow.
- The working section containing sand is for study of the mobile bed formation and to observe two dimensional flow patterns. Wire mesh is provided to contain the sand. Plastics plates are used when two-dimensional flow is to be observed.
- The storage tank collects discharge from the working section and acts as a reservoir. An adjustable overshot weir is provided to control the water level in the working section. The tank also has a sand trap to collect the over-spilled sand.
- A pump to draw water from the storage tank and deliver it to the head tank. A water meter with a flow control valve are also supplied.
- An instrument carriage traveling on stainless steel tube rails attached to the edges of the working section is designed such that the carriage can travel length wise and crosswise over the working section. A stainless steel vernier hook and point gauge is attached to the carriage to measure the sand profile level.
The first three sections are joined together by flanges and the pump unit is connected to the system by flexible hoses. Various accessories are supplied to simulate different flow obstructions and diversions. An aluminium dust or equal is supplied for two-dimensional flow observations.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Sand bed formation under various flow rates.
- Erosion of sand bed around piers or branch canal.
- Two-dimensional flow pattern around pier and branch canal.

Flow Measurement and Flow StudyPiping Loss Apparatus
This is a comprehensive unit for studying the friction losses in pipes, pipe fittings, and valves; and to determine coefficients of discharge for primary flow measuring devices at various flow rates.
All friction loss components and the flow measuring devices are arranged on a water proof panel which is attached to a floor standing steel frame. The apparatus is to be used with a Hydraulic Bench (separately supplied) or an outside water supply.
Friction loss is measured by a pressure drop and coefficient of discharge is determined from a pressure drop and a flow rate. Flow rate is obtained from a water meter and a stop watch. The pressure drop is measured by differential pressure using manometer and differential pressure gauge. Pressure tapping in by small ball valves with quick connection. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses.
The unit is on a steel frame with adjustable footings.
Instruction manual is also included.
