Three Dimensional Equilibrium

Product Code: LBNY-0005-13900015 - (Three Dimensional Equilibrium)

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.

Open Channels Weirs

Product Code: LBNY-0005-15800015 - (Open Channels Weirs)

The flow pattern over a notch or weir is complex and there is no analytical solution to the relationship between discharge and head so that once again a semi-empirical approach has to be used. For small scale applications, weirs are often referred to as notches and invariably are sharp edged and manufactured from thin plate material. Hydraulics Bench incorporates a weir channel which is 158mm wide tapering to 152mm wide at the bottom, x 150mm deep x 735mm long in the working surface. The weir channel is fitted with an acrylic 60 triangular notch weir with an integral scale which can be used to provide an approximate indication of the flow rate. In open channels, weirs are commonly used to either regulate or to measure the volumetric flow rate. The Hook Gauge and Scale is an essential accessory for the accurate measurement of the upstream head. They are of particular use in large scale applications such as irrigation schemes, canals and rivers. For a detailed study of the discharge over weirs, provided two sets of weirs and a hook gauge.

Schlieren Systems

Product Code: LBNY-0005-16200015 - (Schlieren Systems)

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.

Water Treatment Studies Bench

Product Code: LBNY-0005-16300015 - (Water Treatment Studies Bench)

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.

Experimental Capability:
To demonstrate the abilities and combined effects of the base exchange, de-alkalinising and demineralisation units.

Balancing Apparatus

Product Code: LBNY-0005-16500015 - (Balancing Apparatus)

This process is called balancing. The machine component is then balanced and runs without vibration. During imbalance, the principal axis of inertia or centre of gravity of the rotating machine component is outside its axis of rotation. Imbalances on rotating machines are often the cause of disruptive vibrations and noise. By adding or removing masses, the centre of gravity or the principal axis of inertia can be shifted so that both coincide with the axis of rotation. 

Learning Objectives And Experiments:
Comparison of static, dynamic or general imbalance
Demonstration of imbalance vibrations at different speeds
Perform a balancing operation
Determine an imbalance.

Features:
Static and dynamic imbalance.
Representation of the fundamental processes involved in balancing.
