The Aeration Unit comprises an open tank equipped with a paddle stirrer. A variety of diffusers is included. The dissolved oxygen content of the water in the tank is measured by means of an oxygen electrode and dissolved oxygen meter. The equipment consists of a base and backboard standing on four rubber feet. Mounted on the base is the clear acrylic water tank which has a capacity of 24.5 liters. On the front of the tank is a depth scale and at the base a drainage tap. The lid of the tank is partially removable to allow filling. On the fixed part of the lid are mounted the stirrer motor, stirrer and clamping positions for the temperature probe, oxygen probe and aerator tube. Air is supplied by an electrically driven pump through a control valve and flow meter to a diffuser, adjustable for position, within the tank. The meter supplied gives an additional direct reading of water temperature. Air is supplied to the tank by means of a pump with filter and silencer assembly is controlled by a valved flow meter discharging through the aerator tube. Three diffusers, sparger tube, treble airstone and single airstone, may be separately attached to the aerator tube. Operating from internal batteries, the meter may be used for field trials independently of the apparatus. Variable speed adjustment of the stirrer paddle provides different levels of turbulence in the tank. The oxygen/temperature meter is mounted on the backboard with the connecting leads to the appropriate probes.

The transient response of the sensors can be examined by quickly immersing them in the second tank. Digital instruments for measuring temperature, voltage and resistance enable the characteristic curves to be drawn. A wide range of temperature measurements can be performed and compared using this unit. A 3-channel line recorder can be used to continuously record the measured values from the electrical temperature sensors (thermocouple, thermistor, RTD) and thus to document the different responses. The thermometers and temperature sensors to be investigated are heated to the same temperature in a tank of water. A second heated tank with an electronic control system provides water temperatures up to 80C.

This is often seen in an ice skater performing a pirouette. First they spin round on an axis corresponding to their body, arms outstretched. When they raise their arms above their head, the increase in spin in considerable. Conservation of linear momentum is well understood and often demonstrated to students. Rather than go to an ice rink, students can perform this experiments in the laboratory. Equally important is the conservation of angular momentum. It is not easy to do meaningful experiments on this, but a highly visual demonstration of almost dramatic impact is the effect of reducing the radius of a rotating mass.
The resulting increase in angular velocity is considerable.
The weights are moved to the outer ends of their travel, away from the centre of rotation. The arm is then spun rapidly by hand, and the weights pulled towards the centre by the cord.
A bench mounted vertical board has a rotating arm along which two weights can be moved by a pull cord operated by the student or demonstrator.
