An orifice can be screwed into either of the threaded holes and the unused aperture sealed with the blanking plug provided. A scale is mounted on the side of the tank to enable the height of the water above either orifice position to be determined. This arrangement avoids excessive turbulence and enables a steady level surface to be maintained. Two threaded holes are cut into the tank in which to mount the orifice being studied, one in the tank base for 'vertical' discharge, and the other in the tank side for 'horizontal' discharge. The zero of the scale coincides with the centre of the side outlet position. The Orifice sets are used in conjunction with the Inlet Head Tank for the investigation of the flow of water through a horizontal or a vertical orifice. Water is supplied to the tank via a hose connection to the base inlet, and is then distributed within the tank by a vertical perforated sparge pipe. When an orifice is fitted in the horizontal discharge position a Trajectory Profile Hook Gauge can be used to determine the jet profile. Details of both sets of orifices are given as follows.

Most Closed Circuit Wind Tunnels designs are traditional single-return, horizontally arranged circuits. However, any configuration is possible. As with all wind tunnels, exceptionally steady test section flow with close uniformity of velocity is standard. The use of steel for construction offers complete design freedom to meet your unique specifications and needs, such as low overhead clearance or building support columns. Turbulence level is typically below 0.10 percent throughout the full tunnel speed range.

The imbalance of a rotating machine part may cause harmful vibrations in the entire machine. A familiar example is unbalanced tyres on a car. In rotating machines such as turbines or pumps, vibrations due to imbalance lead to comfort problems or even damage related to overloading. If this balancing is done not on a particular machine but directly on the machine in operation located on-site, it is known as field balancing. These cause annoying and unpleasant vibrations in the steering. This is why almost all rotating parts are balanced.
Learning Objectives And Experiments:
Measure and assess machine vibrations
Static, dynamic or general imbalance
Occurrence of imbalance vibrations
Field balancing in one plane
Field balancing in two planes
Dependence of imbalance vibration on position and magnitude of the imbalance
Basic principles of balancing
Using a computerised vibration analyser
Assessment of balancing quality.
Features:
Single and two-plane balancing
Measurement of imbalance vibrations.

The Motor Exciter assembly houses two out of balance masses, which when rotated at speed, created a sinusoidal excitation. This excitation motion is transmitted to the test beam, which starts to vibrate. The frequency of vibration changes with the changing speed of the motor. The Motor Exciter is an essential part of the Universal Vibration Apparatus. Motor Exciter primary function is to transmit rotational motion into linear displacement of a beam, and hence force the beam to vibrate at varying amplitudes and frequencies. The Motor Exciter is controlled by the speed control unit. All the connection cables and sockets are factory fitted. A proximity sensor mounted to the rear of the motor gives the signal to the Tachometer. The Motor Exciter is clamped onto a rectangular beam, in the desired position, i.e. onto the beam within Free and Forced vibration module.
