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 axially discharged water from the turbine impeller can be observed. The number of active nozzles can be adjusted by valves. The eddy current brake generates a defined load. The experimental unit is placed upon the base unit. The two units together provide the basic experiments to get to know the operating behaviour and the most important characteristic variables of action turbines. Action turbines operate according to the principle of equal pressure. The water jets are deflected in the turbine impeller and put it in motion. The eddy current brake is specially developed by.The torque delivered by the turbine is determined via an electronic force sensor. The speed is measured with an optical speed sensor. The static pressures at the inlet and at the outlet of the impeller are equal. The water jets are discharged with high velocity from four nozzles of the distributor.

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.
