UNSTEADY STATE HEAT TRANSFER UNIT

Product Description

Specification:

UNSTEADYSTATE HEAT TRANSFER UNIT

This Unsteady State Heat TransferUnit has been designed to allow students to run experiments on unsteady stateheat transfer. The unit is supplied with a heated water bath and a set of solidshapes with built-in temperature sensor to monitor the temperature at thecenter of the shape. Monitoring of the temperature at the centre of the shapeallows analysis of heat flow using the appropriate transient-temperature/heatflow charts provided.

Description

Two sets of simple shapes (a solidsphere, a rectangular slab, a long solid cylinder) made of brass and stainlesssteel are supplied. Each of the shapes has a built-in temperature sensor tomeasure the temperature at the centre of the shape. Measurements taken on ashape of a particular material can be used to confirm the conductivity of asimilar shape of a different material.

Transient-temperature/heat flowcharts are supplied for each of the shapes. The water bath has a capacity of 30litres and is heated by a 3.0 kW electric heating element. The temperature ofthe water bath can be maintained and predetermined by means of a temperaturecontroller before taking any measurements. The large volume of water in thebath ensures that any change in the temperature of the water, as themeasurements are taken, is negligible. A circulation pump mounted alongside thewater bath circulates water from the bath to the base of a vertical cylindricalduct which is located at the centre of the water bath.
