Pascals Law Demonstration system is designed for the study and demonstration of the Pascals principle enunciated by the physicist and mathematician Blaise Pascal it states that the pressure, exerted anywhere in a confined incompressible fluid, is transmitted equally in all directions throughout the fluid so that the pressure variations remain the same. There are many applications based on the Pascals principle and one of the best known is the hydraulic press. With Pascals Law Demonstration equipment, it is possible to study the "hydrostatic paradox" that is a consequence of the Pascals principle: the pressure within the liquid at rest depends only on the depth of water, regardless of the quantity.

An exploded-view of the jig is printed on the cover to illustrate the construction of the jig. A quarter segment has been cut out of the main body of the drilling jig. The basis for the course is a drilling jig which can be used to drill holes in a bearing cover. All drilling jig components are clearly laid out on a base plate. The cut-away quarter segment is also present on the base plate, enabling the difficult topic of sectional views to be illustrated. All parts are precision-manufactured on cnc machines and are therefore also suitable for measurement exercises. It can facilitate the drilling of the workpiece and other small parts. This enables demonstration of the terms 'section' and 'half section' as used in technical drawing. The comprehensive instructional material is laid-out in line with modern principles and provides effective assistance with lesson preparation. Optimal learning is established when groups of two or three students work on one model.

The channel is totally transparent so it allows an optimum visualization of the hydraulic flow. The purpose is to study the flow behavior in open channels and closed pipes, by realizing some experiments in both conditions. These points are connected to the 6 tubes manometer. By floodgates, it is possible to increase water volume in the inlet or outlet tanks. In order to carry out experiments in a closed chamber, the module includes a cover for hermetically seal. Pitot tubes are arranged along the whole length of channel, so it allows measuring the working pressure in 6 points. The equipment can be used stand alone or in conjunction
Open channel:
1. Study of water flows through open channels identifying variables like:
Speed at different points of the cross-sectional area.
Water height
2. Study of constant water flow, gradually varied flow and behavior of surface profiles.
3. Study and utilization of thin edged weir for flow measurements.
Rectangular weir without lateral contraction.
4. Study and utilization of broad crested weir for flow measurements.
Rectangular weir.
5. Analysis and study of discharge under a gate.
Vertical weir
6. Study of jump spillway

A fan with a flow control valve is connected to the bottom tank, and air is driven upwards through the column and exhausted at the top. Instrument are provided for measurement air flow rate, water flow rate, pressure drop across the cooling tower, temperature and moisture of the inlet and outlet air. This is a Cooling Tower Demonstration Unit. Water is heated in the storage tank, pumped through a flow meter and sprayed at the top of the tower. The water is cooled mainly by evaporation and drops to the bottom tank. Makeup water is admitted to the storage tank through a float valve. The packing in the tower breaks the water into thin films and droplets.
Experiments:
Application of steady flow equation to energy balance.
Cooling tower performance at various air and water flow rates with different inlet water temperatures.
Observation of water flow patterns and distribution.
Measurement of water and air flow rates, temperatures and humidity.
