It comprises the calorimeter, a calorimeter vessel, an outer double walled water vessel, electric stirrer gear, combined motor control gear and ignition unit, a Beckman type thermometer, and a charging unit with pressure gauges to facilitate the charging of the calorimeter with oxygen. The equipment is self-contained with the control unit housed in an instrument case that forms the base. A Briquetting Press is available as an optional extra and an additional calorimeter can also be supplied. No spanners are required and in use the rubber joint is protected by water so it may be used over and over again. The particular features of the calorimeter are the method of sealing and the method of ensuring ignition. The body of the calorimeter is screwed into the base and a seal is made with a special rubber joint when the two parts are finger-tight only. In order to make ignition 100% sure, great care has been devoted to the method of anchoring the ignition wire and maintaining electrical contact and to the support of the crucible. All these parts are made to a high degree of precision and the results are very satisfactory.

The unit is designed for blow or suction induced flow and can be assembled for operation in either the upward or downward mode, whichever is most convenient. The Aeroweb honeycomb matrix is suspended within a cylindrical, aluminum housing with the skirt of the matrix immersed in an annular oil reservoir in the base which serves both as an air seal and a viscous damper. A set of weights is provided with the instrument to facilitate static calibration of the strain gauge with an accuracy of 2%. The matrix is mounted on an axle in the frame and supported by precision ball bearings while the torque arm connected to the axle acts on a Wheatstone Bridge strain gauge transducer. Cussons Display Unit, used in conjunction with the swirl meter, is a mains operated instrument complete with power supplies, which converts the strain gauge measurement into a four element, LED digital readout.
Application:
In automotive and truck size engines for instance, a pressure drop of 254 mm water gauge is normally used. The illustration shows a typical test rig layout arranged for downward air flow, in which the clients manometer registers a constant pressure drop across the model which must always be high enough to ensure fully turbulent flow in order that the results can be applied to his own particular engine configuration.

A heat exchanger coil is built into the reservoir such that the water temperature within the reservoir can be controlled by allowing cooler mains water to flow through the heat exchanger coil. This experiment includes a shallow heat collection tray approximately 1.2 m by 1m, the base of which is fitted with removable heat capture material. Water is pumped through the heat transfer plate, on the tray, and is returned to an insulated reservoir mounted on the base of the unit The water is continuously re-circulated through the transfer plate so that the temperature in the reservoir gradually builds up. An inclinometer to indicate the degree of tilt is available as an optional extra. This material assists in the heat transfer process. The heat capture and transfer plate is itself covered by a sheet of flat plate glass, which captures the radiation and reflects light back to the heat.

The flexible design of the equipment allows the user to develop many other analysis and control exercises to suit their needs. It is good for extended or advanced control experiments, and is ideal for student project work.
Reversible Pendulum Apparatus can be suspended from either pivot and swung. The two pivots are adjustable on the rigid metal bar and this allows the periods of swing to be adjustable. The Reversible Pendulum Apparatus consists of a rigid metal bar with two pivot points, one near each end of the bar.
The movable pivot is adjusted until the two periods are equal. From the period and the measured distance between the pivots, the acceleration of gravity can be calculated with great precision. In use, it is swung from one pivot, and the period timed, and then turned upside down and swung from the other pivot, and the period timed. At this point the period is equal to the period of an ideal simple pendulum of length equal to the distance between the pivots.
Experimental Capabilities:
To find the acceleration due to gravity 'g'
Investigate the effect of fulcrum position.

Two Phase Flow occurs when a gas is flowing in a confined space with a liquid. The flow profile and geometry in this instance varies widely as a function of the liquid and gas material properties as well as the flow rates through the pipeline. The Two Phase Flow Demonstrator apparatus is a small scale flow loop that can demonstrate Two Phase Flow phenomena in pipes at a variety of liquid and gas flow rates. It is important that the process operator understand the basics of Two Phase Flow Demonstrator in pipelines, especially as it pertains to the formation of the destructive slug flow regime. Certain flow regimes can be destructive to facility piping, and should be avoided where possible. The destructive effects of these flow regimes can be managed through the use of various piping geometries.
The air and water flow rates are continuously variable over a wide range of flow rates. This allows the operator to observe a wide range of two-phase flow regimes using this demonstrator. The Two Phase Flow Demonstrator is mounted on a movable cart for ease of movement and storage. Two Phase Flow Demonstrator uses air and water to create different flow regimes in the process piping. Air is supplied to the system by a low pressure blower, and water is supplied through a centrifugal pump.
