The model consists of two hooke's couplings that are connected by a split intermediate shaft. The deflection angle of both joints can be set individually and read on the scales. Drive is achieved by turning a hand wheel. On the drive and power take-off sides there are further angle measuring scales made of transparent plastic with which the difference between the angles of the shafts can be determined. The table model demonstrates the transmission of angular motion to joint shafts, the related gimbal error and how this error can be rectified using hooke's couplings.

The bourdon gauge and pressure sensor are mounted on a manifold block with a separate reservoir to contain the hydraulic fluid water for safety and ease of use. Valves enable easy priming, restricted flow of water to demonstrate the application of damping and the connection of alternative devices for calibration.
A bench top unit designed to introduce students to pressure, pressure scales and common devices available to measure pressure.
The DPC consists of a precision ground piston and cylinder with a set of weights giving an operating range of 20 kNm-2 to 200 kNm-2.
The equipment utilises a dead weight pressure calibrator DPC to generate a number of predetermined pressures. This is connected to a Bourdon gauge and electronic pressure sensor to enable their characteristics, including accuracy and linearity, to be determined.
The eccentric shaft is guided onthe drive side by a roller bearing and opposite by a plastic friction bearing. Also cutaway: fuel return with shut-off attenuator, quantity control valve with magnetic coil and filter. The necessary high pressure is generated by a 3-plunger radial-piston pump with the following features: compact construction, stainless steel housing with integrated quantity control valve, fuel-lubricated, shut-off attenuator, max. fuel pressure of 200 bar. The knurled screw can be used to drive the high-pressure pump and one sees how the pump pistons work.

These studies focus on topics such as seepage and flow of water in the soil and the use of groundwater resources. Can be used to study seepage and groundwater flows after precipitation. In civil engineering, studies in hydrology are conducted in connection with the design, construction and operation of hydraulic engineering systems and water management functions. The core element of the trainer is a sand-filled, stainless steel experiment tank with inclination adjustment. To illustrate groundwater flow, the water is supplied via two side-mounted chambers. In particular, permeability and storage capacity of soils can be clearly observed. At the bottom of the experiment tank there are measuring connections to detect groundwater levels. A mirrored arrangement of the measuring connections allows for a finer resolution of the measurement. Variable precipitation density and areas and different groundwater feed and discharge possibilities allow a wide variety of experiments.

The apparatus consists of a through pipe conveying water from a cold water supply to a suitable drain with a loop of pipework connected between the supply and drain connections. The heater can be switched on or off to generate step changes when investigating the transient responses of the recycle loop. This recycle loop incorporates a circulating pump and a heater to raise the temperature of the water in the loop.
A bench top unit designed to introduce students to the characteristics of a recycle loop and the typical responses under steady state and unsteady state conditions.
The arrangement also permits different lengths of flexible tubing to be connected in series with the loop if it is required to create further changes in residence time. A pair of self-sealing fittings enables a short length of pipe or a reservoir to be connected in series with the recyle loop to change the volume of the loop and demonstrate the effect of residence time.
