The equipment consists ofa vertical panel that holds a clear plastic quadrant, to which students addwater. The quadrant has engraved lines to help students keep the plane in avertical or angled position. The cylindrical sides of the quadrant have theircentral axis coincidental with the moment measurement axis. This product allows students to measure the moment due tothe fluid (hydrostatic) thrust on a fully or partially submerged plane. The plane works in either a vertical or inclined (angled) position. Students thencompare their measurements with theoretical analysis. The total fluid pressures on these curved surfaces therefore exert no moment about this pivot.Therefore, the moment is only due to the fluid pressure on the plane testsurface. Students measure this moment using weights suspended from a level arm. A scale on the panel of the apparatus shows the head of water. They then initially balance the quadrant tank using one of the weighthangers and the smaller trimming tank. They take results by balancingincremental weights on the hanger with known quantities of water. To performexperiments, students level the apparatus using its levelling feet and spirit(bubble) level. They decide whether to test either a vertical or inclinedplane. Students note the relationship between the moment and the water height(h). They then usethe results to calculate the equivalent moment of force (M) or hydrostaticthrust.

Pumps in a pipe system are used to convert mechanical energy into hydraulic energy this additional energy allows a fluid to move when it is not possible by gravity and for example, to raise a fluid at a certain height above the pump or make it recycle in a closed system. The working principle of a centrifugal pump is based on the fluid inlet in the middle of the impeller, which blades conduct the fluid and thanks to the centrifugal force it is driven outward. In general, the main purpose of a pump in a system is to increase the total energy H. At this point, the fluid is collected and contained by the pump casing which, thanks to its shape, drives the fluid to the outlet pipes or to another impelling stage.

The Oil Pump Supply Module is part of an equipment series that facilitates the investigation of a wide range of engines and machines. The flow is adjusted on a pressure valve and recorded using an oval wheel meter. Other sensors measure the temperature, intake and delivery pressure. Different oil pumps can be operated on the supply module and investigated in terms of their characteristic behaviour. The corresponding sensor connections and digital displays are located on the measuring equipment block. The pumps are connected into the experimental set-up using hydraulic hoses with quick action couplings.
....
The air flow rate can be measured with various measuring inserts such as a nozzle/orifice, Pitot tube or iris diaphragm. The measuring inserts are connected to a multiple tube manometer using hoses; the pressure differences can then be read on the manometer. The system offers comprehensive investigations on air flow. A fan draws air through a section of pipe. The tube manometer can be tilted to increase precision and can be fixed in various positions. Open jet experiments can be performed at the fan outlet. Measuring glands are also fitted to the pipe section at evenly spaced intervals; these can be used for determining pipe friction, pressure losses or velocity profiles.
....
The individual accessory modules are driven using a DC drive motor. The motor is connected to the controller. The rotational speed can be continuously and finely adjusted using a 10-turn potentiometer. The speed is regulated electronically and displayed digitally. Friction forces are measured using strain gauge transducers. The trainer enables different sliding and rolling friction cases to be investigated. The parameters of a tribological system can be assessed during this process. The drive module is the basis for experiments with a range of accessories. Snap-action fasteners for fixing the accessory modules to the frame simplify the rapid assembly and disassembly of the experiments. The unit consists of a sturdy frame made of anodised aluminium section. Rubber feet ensure that the table unit does not slip. The controller processes this data and displays it digitally.
....
The models supplied are made of plastic and are equipped with connections for pressure measurement; these are connected to the Computer Linked Air Flow Bench. It is possible to investigate the pipe friction losses in a flow of air for different fittings such as a straight pipe section, an elbow, a bend, and different pipe inlets.
....
A transparent pipe bend with a constant square cross-section is attached to the test stand using quick action fasteners. The measuring gland are connected to the Multi Tube Manometer. The pipe bend is equipped with measuring glands at regular intervals for measuring the pressure loss.
....
The experimental arrangement is clearly laid out on a demo panel. The panel is fitted to a laboratory trolley and is thus flexible in use. For the investigations on the pipes, 10 different pipe sections are provided in which measuring connections with annular chambers are incorporated. The flow rate is indicated on a variable-area flow meter. An instruction manual with detailed description of the theoretical background is supplied. Only a supply of cold water and a drain are required for operation.
....
A ball sinks to the bottom under the action of gravity. The sink time and distance are measured. Included with the unit are a stopwatch and 10 spheres of different materials and volumes. At the bottom of the measuring tube is a chamber through which the balls can be removed without major loss of fluid. Two Plexiglass cylinders are provided for performing the experiment, these are filled with fluids of varying viscosity.
....
Piston pumps are used when high pressures are to be generated. The flow rate of piston pumps is independent of the head and is determined only by speed. Its good suction performance is outstanding. Piston pumps belong to the group of positive displacement pumps. They transport the medium by a reciprocating motion of a piston in the pump working space, called stroke. The stroke creates a suction respectively vacuum effect used to deliver the water. The pulsating pressure curve of the pump can be damped with the aid of the air vessel. Flow rate and head are adjusted via needle valve and overflow valve. The experimental unit is fitted with sensors for pressure and flow rate. The cycle that takes place (intake and discharge of water) can be shown clearly in the p-V diagram. The position of the piston rod is measured by an angle sensor. This allows the determination of the cylinder volume. One pressure sensor measures the pressure at the outlet of the pump, another one measures the pressure in the inside of the cylinder.
....
The unit incorporates a pressure sensor to measure the inlet condition of the water. The consists of a return tube incorporating a gate valve, which can be attached to the pump outlet on the service unit.

A precision-machined base plate holds the motor and its sensors. The Universal Dynamometer directly drives the Fluid Power machines. This means that the user has no need to fit or adjust the tension of belts and pulleys. The coupling between the Universal Dynamometer and all Fluid Power machines is a jaw-type coupling with a rubber element. The base plate has location points to give accurate and repeatable alignment onto each Fluid Power module.
The front of the motor drive and display unit has motor stop, start and speed controls. Outlets on the back of the unit give power for instruments supplied with the Fluid Power modules. The motor drive and display unit contains a variable-speed a.c. inverter drive and includes signal conditioning. It digitally displays speed, torque and shaft power. This reduces the need for multiple mains connections and gives a neater and safer equipment arrangement. The unit fits on the instrument frame fitted to all the Fluid Power modules.

The permanent arrangement of PVC pipes and fittings is mounted on a freestanding support frame that is designed to stand alongside Hydraulics Bench in use.
Self-sealing quick release fittings at strategic points in the network allow rapid connection of the digital hand-held pressure meter, allowing appropriate differential pressures to be measured. Flow leaving any of the outlets in the network is measured using the volumetric facility incorporated on the Hydraulics Bench.
All clear acrylic test pipes are installed using threaded unions with 'O' ring seals that allow the pipes with different diameters to be repositioned without the use of tools.
Isolating valves allow a wide range of different series, parallel and mixed pipe configurations to be created without draining the system. Flow into the network and flow out from the network at each outlet can be individually varied to change the characteristics of the system.
The Osborne Reynolds' Demonstration operates in a vertical mode. Flow through this pipe is regulated using a control valve at the discharge end. A header tank containing stilling media provides a constant head of water through a bellmouth entry to the flow visualisation pipe. Velocity of the water can therefore be determined to allow calculation of Reynolds' number. The flow rate of water through the pipe can be measured utilizing the volumetric tank (or measuring cylinder) of the Hydraulics Bench.
The equipment uses a similar dye injection technique to that of Reynolds' original apparatus to enable observation of flow conditions.

This Pascals Apparatus, developed to demonstrate principle of Pascal, consists of a machined body incorporating a horizontal flexible diaphragm to which one of three alternative glass vessels can be fitted. The diaphragm, located at the base of the vessel, conveys the force from the water inside the vessel to a lever arm with a sliding counterweight. The force on the diaphragm depends on the depth of water above the diaphragm and the area of the diaphragm that is constant for all three vessels. A spirit level indicates when the lever arm is horizontal and therefore balancing the force / pressure at the base of the vessel. The diameter at the base of each vessel is common but the shape of each vessel varies; one parallel sided, one conical and one tapering inwards.
