Unsteady State Heat Transfer Unit
Product Code : JA-HTLE-7381
The Unsteady State Heat Transfer Unit (SKU JA-HTLE-7381) shows how the temperature of a solid changes with time when it is suddenly placed in a hotter fluid. A small test cylinder is immersed in a hot water bath held at constant temperature, and a sensor at its centre records the temperature until steady state is reached. This transient heat conduction apparatus has a bath heater with digital temperature controller and an agitator to keep the bath uniform.
Specifications
The unsteady state unit is described by its test cylinder with centre temperature sensor and a hot water bath with heater, digital temperature controller and agitator. Cylinder material and size, bath volume and heater rating are not in the listing and are confirmed on the quotation.

Experiments with the unsteady state heat transfer unit
The unit is used to record the centre temperature of a cylinder against time during heating and to use the curve to find the heat transfer coefficient and the dimensionless numbers of transient conduction.
- Calculating the Biot number and Fourier number
- Finding the surface heat transfer coefficient from transient data
- Plotting centre temperature against time
- Transient conduction practicals in B.Tech and diploma courses
