Influence Line Apparatus
The equipment is used for studying the reactions under various conditions of load at all supports along a three-span bridge. It is to be used with ST300 Universal Structural Frame (separately supplied).
The bridge has a cantilever end sections and a suspended center section. The location of the supports is adjustable.
The supports are vertical force supports for measurement of loads. The deflection of the bridge can be measured by dial indicators.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Influence lines for supports and internal reactions due to a load moving across the beam structure.
- The effect of loads to bridge support reactions and internal reactions between the cantilever and suspended sections.

Air Flow and ThermodynamicsShell and Tube Heat Exchanger
The apparatus is used for studying heat transfer through a shell and tube heat exchanger under parallel or counter flow conditions.
The unit consists of a shell and tube heat exchanger and a service module. The module comprises a hot water tank with a transfer pump and instruments for monitoring and control. Parallel and counter flow is by switching cold water hoses with quick coupling. The unit requires outside water supply.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Demonstration of heat transfer under parallel and counter flow.
- Determination of heat transfer coefficient.
- Effects of flow rate and temperature difference.

Mechanics of FluidsBasic Hydrology Apparatus
The apparatus is a self-contained unit for studying basic hydrology.
It consists of a large stainless steel rectangular tank with adjustable tilting mechanism. The tank is filled with a granular medium. Two separate sets of four spray nozzles above the tank simulate rain fall on the catchments. The tank upper walls are transparent. Valve control of the nozzles varies the lag time on the hydrograph to simulate a moving storm.
The compartments at each end of the tank are connected to the catchment area by wire mesh to allow flow between the compartment and the catchment. Two wells with valve control are also provided at the middle of the tank. Twenty pressure tappings along the orthogonal axes of the tank measure water table profile by a manometer bank.
A metal frame supports the tank and houses a storage tank. Water is drawn from the storage tank by a pump and separately supplied to the overhead nozzles and/or the two end compartments via a flow meter and pipings with valve control. Run-off from the catchment is measured by a calibrated rectangular weir or returns directly to the storage tank.
Instruction manual is also included.
TYPICAL EXPERIMENTS- Investigation of rainfall/runoff relationships for dry, saturated and impermeable catchments of various slopes for surface runoff.
- Effect of interflow on outflow hydrograph
- Simulation of multiple and moving storms.
- Cone of depression for single well and interaction of cones of depression for two adjacent wells.
- De-watering of excavation sites by use of wells.
- Flow from a well in a confined aquifer.
- Demonstration of watersheds for a simulated island with rainfall and well flows.
- Sediment transport and meanders in simulated rivers.
