This apparatus is for demonstration of simple balancing techniques.

It consists of a balanced steel shaft mounted on two self-aligned ball bearings on a rigid frame with rubber footings to minimize vibration. Four different balance masses, which can be easily clamped on any position on the shaft are provided.

For static balancing, an extension shaft with a pulley is fitted to one end of the shaft. Two weight containers with a cord are wound around the pulley. Steel balls are then added to one container until the shaft is in equilibrium to determine the maximum moment of each balance mass. An angular scale is attached to the other end of the shaft and a linear scale is attached along the frame parallel to the shaft to measure angular and linear positions of each mass.

For dynamic balancing, the shaft assembly is driven by a fixed speed motor via a belt. In the case of unbalance, the shaft will vibrate and the vibration is absorbed on the rubber footings. A safety guard with transparent front is provided.

Instruction manual is also included.

  • Static balancing of the system using moment polygon.

  • Dynamic balancing of the system by calculating positions of the masses along the shaft and by resolving and taking moments

       about one end of the shaft.

The machine is used for studying of balancing principles.

A rotor shaft is connected to the motor by a double universal joint and rests on two supports with adjustable distance between supports. Each support holds the shaft in place by three bearings with crest. Two standard rotors and two radially slotted rotors are provided for various cases of balancing. The unbalance forces are picked up by two vibration transducers and converted to digital signals. The speed is adjusted by an inverter and speed signal is provided by a sensor. The magnitude and angle of the unbalance for each plane is analyzed and displayed on a computer (separately supplied). The vibration and speed transducers are removable for field use.

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.

  • Investigation of rainfall/runoff relationships for dry, saturated and impermeable catchments of various slopes for surface runoff.

This is a bench top self contained water circulating unit for studying the various flow measuring instruments including primary flow measuring devices.

The flow measuring instruments are connected in series and all except the measuring tank are arranged on a water proof panel.

Measurement of flow by a primary flow measuring devices is by coefficient of discharge which is determined from a pressure drop across the device and a flow rate. Flow rate is obtained from a water meter reading and a stop watch. The pressure drop is measured by deferential pressure using manometers. Pressure tapping is by small ball valves with quick connection. Water tanks are behind the panel. Flow rate is varied by a flow control valve.

Instruction manual is also included.

  • Comparison of differential pressure at various flow rates for Venturi meter, orifice meter, Pitot tube, and variable area flow meter.
