The compressor is driven by a variable speed d.c. electric motor with a belt gearing-up system of O to 4000 RPM with a transmission ratio of 7.5/1.If is possible to read the pressure values, upstream and downstream of the compressor, by means of 2 U shaped differential manometers. The industrial type compressor used in this apparatus is a single stage machine having a 127 mm dia impeller and an aluminium scroll with fluid threads rectifier. Thermometers are inserted into the circuit in order to read the air temperature before and after the passage through the centrifugal compressor. At the maximum speed of over 29,000 RPM, if develops a downstream pressure of about 230 mmHg with a max air capacity of 1230 kg/h.

The Three Dimensional Equilibrium equipment is used for studying the equilibrium of five concurrent and non-concurrent forces in a three dimensional system. A vertical load with a cord is applied at one of the joints. Each cord is marked out a 100 mm length. Two mirrors are attached on two adjacent side walls and transparent plates with transparent graph grids are attached on the other two side walls. Four cords, each with a load hanger outside the frame, pass over the pulleys and meet inside the frame concurrently or non-concurrently with an additional cord between two joints. By aligning each marked cord to the mirror, its coordinates in space can be measured. A rigid box frame has four swiveling pulleys at the top corners and leveling screws at the legs.

The Diaphragm And Piston Pumps Test Unit is completely self-sufficient and it is fitted with a wheeled frame the working liquid is the water. The reciprocating pumps fitted with the bench are micro metrically regulated by the piston upstroke this allows to change the volume of the pumping chamber and consequently to modify the delivered capacity without reducing the delivery pressure.
The group is supplied with manuals which describe all parts of the Diaphragm And Piston Pumps Test Unit, the installation and utilisation procedures, aswell as many exercises with the relative results. The Diaphragm And Piston Pumps Study unit allows the student to understand and to experiment the reciprocating pumps running.
In supersonic flow, air experiences very large changes in density as it approaches, passes through and trails shock waves. As the density of air changes, so does its index of refraction. Schlieren Systems let you see shock waves as a combination of bright and dark areas. In the study of supersonic flow, shock and expansion waves are used to determine Mach number. Schlieren are optical in homogeneities in transparent materials. In most situations, however, they are virtually invisible to the naked eye.

A panel with tubular supports is provided for storing filter columns not in use. Dosed or untreated water is transferred from the sample tank to the filter system by a centrifugal feedwater pump at reduced pressure and a metered rate; treated filtered water is either collected in a portable 25 litre storage tank or passed to the Steam Boiler Bench, depending on the use of the unit. Water Treatment Studies Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. These are fitted with top and bottom quick release couplings. Two of the columns may be used at any one time in a system of inter-connecting pipework and selection valves, set to allow the columns to be circulated with dosed or untreated water either independently, in parallel, in series or in reverse, and with a backwash connection from the service water line. The studies bench comprises five interchangeable, clear filter columns, each of which can be filled with a sand filter or ion exchange medias. A variable chemical dosage system, comprising a dosage pump and a chemical additive mixing vessel, is supplied to inject diluted additive at a controlled rate to either a portable 25 litre sample tank or the boiler feedwater tank on the Steam Boiler Bench. A control box, suitable for either 110V or 240V a.c. supplies, provides separate ON-OFF switches and associated indicator lamps for each pump and a switch to select the pumps for either Water Treatment Studies or Feed Water Service to the Steam Boiler Bench. Pressures at the inlet and outlet of either filter column are indicated on separate 0-2.5 bar Bourdon tube pressure gauges. Sample cocks are included in the system to enable water samples to be collected for analysis by test kits supplied with the unit.
