UNSTEADY STATE HEAT TRANSFER UNIT

Product Description

This Unsteady State Heat Transfer Unit has been designed toallow students to run experiments on unsteady state heat transfer. The unit issupplied with a heated water bath and a set of solid shapes with built-intemperature sensor to monitor the temperature at the center of the shape.Monitoring of the temperature at the centre of the shape allows analysis ofheat flow using the appropriate transient-temperature/heat flow chartsprovided.

Description

Two sets of simple shapes (a solid sphere, a rectangularslab, a long solid cylinder) made of brass and stainless steel are supplied.Each of the shapes has a built-in temperature sensor to measure the temperatureat the centre of the shape. Measurements taken on a shape of a particularmaterial can be used to confirm the conductivity of a similar shape of adifferent material.

Transient-temperature/heat flow charts are supplied for eachof the shapes. The water bath has a capacity of 30 litres and is heated by a3.0 kW electric heating element. The temperature of the water bath can bemaintained and predetermined by means of a temperature controller before takingany measurements. The large volume of water in the bath ensures that any changein the temperature of the water, as the measurements are taken, is negligible. Acirculation pump mounted alongside the water bath circulates water from thebath to the base of a vertical cylindrical duct which is located at the centreof the water bath.
