The product consists of a transparent vessel on a support frame, which mounts on a DigitalHydraulic Bench. A low-voltage, variable-speed motor rotates the vessel aboutits vertical axis. The Vortex Apparatus enables students to produce both freeand forced vortices, and measure the vortex water surface profile. To produce a forced vortex, studentsadd water to the rotating vessel until it is about half full. A forced vortexforms. After a few minutes the vortex becomes constant, and students canmeasure the surface profile using the traverse probe. A speed-control unit (included), sited away from the mainapparatus, controls the speed of rotation. Students can also measure distribution of total head by replacing the traverseprobe with a Pitot tube. The traverse probe canmove both horizontally and vertically, and both axes have linear scales.

The primary separation operation for crude oil occurs when the crude stream flows through a vessel of sufficient capacity to allow gravitational separation of the gas, liquid hydrocarbon and water phases. This fluid mixture then flows into a horizontal separator vessel fabricated of clear PVC. Gas flow passes through a secondary vertical 2-phase separator. This process trainer blends air, water and refined oil to emulate a crude oil stream. The entire trainer is controlled from an optional distributed control system or dedicated control panel. The separator is equipped with industry-typical process measurement devices.

This experimental unit forms part of a series of teaching systems developed in collaboration with the Department of Automation and Information Technology at the Harz University of Applied Studies and Research. A fuzzy control will be developed and optimised for this purpose. The inclination of the pendulum is measured by a potentiometer. The unstable "inverted pendulum" system acts as a mechanical single-variable system. The upright position of the pendulum is adjusted by two independent propeller drives and should be achieved quickly and if possible without overshooting. This output value controls the actuators, two propeller drives. The sensor supplies a crisp signal to the fuzzy controller, where the signal is transformed into a fuzzy input value and inferenced before being transformed back into a crisp output value.

The boiler produces steam to turn a two-cylinder steam motor. The used steam from the motor outlet passes through a mains water-cooled condenser, then down to a waste tank or to a measuring vessel (supplied). The equipment includes all instruments needed for the experiments. A mobile frame contains all the parts of the test set. An electric pump draws from a reservoir to deliver water to an electrically-heated boiler. The boiler includes a safety valve, water level gauge and blow-downcock. Thermocouples connect to a digital temperature display to measure and display temperatures at key points in the test set. Athrottling calorimeter allows students to measure the dryness fraction of the steam. Two mechanical gauges show the boiler and engine inlet pressures. These include a band-brake dynamometer with a digital torque and speed display, to measure and display motor speed, torque and power.

Measurement of rates of water penetration into the soil is aided by a grid on the tank front. The equipment is self-contained with a sump tank, pump and flowmeter fitted behind the tank. Water may be discharged along the soil surface or directed to twin drip nozzles to demonstrate trickle irrigation.
Removable end plates allow soil samples to be changed quickly and easily.
The apparatus consists of a narrow transparent fronted tank which may be partially filled with any soil type. It is supported on a bench mounted frame.
A simple measure of whether the liquid is filterable is useful to enable assessment of filtration as an appropriate process, if so what type of pre-treatment and filter media are required. The use of deep beds of porous granular media to filter liquids to improve their clarity is widespread in municipal and industrial practice. Other liquids are filtered through granular media in the processing of beverages and food products for example. Predominant is the filtration of drinking water and industrial water, although the filtration of sewage as a tertiary stage of treatment is increasing. Although the normal methods of chemical and physical analysis such as suspended solids content, turbidity, color etc. may, with experience, indicate whether a suspension is filterable, they give no direct measure of this property.
The Filter ability Index Unit utilizes a bed of granular material, normally sand, which can be chosen by the investigator to suit his own purposes. The measurements taken with this apparatus enable a filter ability number to be calculated which has significance in deep bed filter performance.
A number of measures of filter ability have been proposed, using woven micromesh, lint pads or membrane filters, which have application where these materials represent, or are identical to, the filter media to be used. However none of them is representative of porous granular filter media, such as sand, consequently they are not applicable to deep bed filtration.
The Filter ability Index Unit is not intended for filter design purposes. That requires pilot filter column equipment such as the Deep Bed Filter Column. However preliminary assessment of pre-treatment processes, and possible filter media with the Filter ability Index Unit will reduce the amount of testing required with pilot filter columns.
