About UNSTEADY STATE HEAT TRANSFER UNIT
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.
Specifications
A benchtop unit designed to allowexperiments on unsteady state heat transfer.
Bench made of epoxy coated frame withhigh quality and sturdy Formica laminated back panel.
Water Bath: 30 liters insulatedstainless steel tank with top plate and mounting for solid shapes holder.Heating is by a 3.0 kW electric heater with high temperature cut-outprotection. Water circulation by a circulation pump.
Solid Shapes: Two sets of solidshapes made of brass and stainless steel complete with shape holder. Threedifferent shapes i.e. solid sphere, rectangular slab and long solid cylinder.Each solid shape has a built-in temperature sensor at the center.
Control Panel: The control panelincludes all the necessary electrical wiring, digital indicators andtemperature controller
Comprehensive Heat Transfer Training
This laboratory-scale unit introduces students and researchers to unsteady-state heat transfer measurement, allowing hands-on experimentation with either copper or aluminium rods. The adjustable temperature range up to 150C and digital indicators make it suitable for a variety of training and testing scenarios.
Robust Safety and Easy Data Management
The heater includes an over-temperature cut-off for safe operation, while the vessels glass wool insulation minimizes heat loss. The integrated control panel with digital readouts and the external data logger port streamlines experimental setup and facilitates easy recording and analysis of data.
Flexible and Accurate Experimentation
Six strategically placed thermocouples enable detailed temperature profiling along the experimental rod. The units natural convection cooling setup, adjustable parameters, and semi-automatic operation deliver high measurement reliability and flexibility for laboratory investigations.
FAQs of UNSTEADY STATE HEAT TRANSFER UNIT:
Q: How is the Unsteady State Heat Transfer Unit typically used in laboratories?
A: This unit is primarily used to study the transient (unsteady) heat conduction behavior in metallic rods, such as copper or aluminium, by monitoring temperature changes over time at various points using thermocouples. It is suitable for undergraduate and research-level experiments in heat transfer courses.Q: What safety features does the unit offer during operation?
A: The equipment incorporates an over-temperature cut-off mechanism, which automatically shuts off the Nichrome heater if the temperature exceeds safe limits. Additionally, high-grade glass wool insulation helps to safely contain heat within the vessel and prevent accidental burns.Q: When should you use copper versus aluminium rods for experiments?
A: Choice of rod material depends on the experimental objective. Copper provides a higher thermal conductivity, allowing rapid heat transfer, whereas aluminium offers a different rate of heat conduction. Using both helps in understanding material impact on unsteady-state heat transfer rates.Q: Where is experiment data recorded and monitored?
A: Temperature data measured by the six thermocouples is displayed digitally on the integrated control panel. The apparatus also features an external data logger port, enabling straightforward recording and further analysis of experimental results.Q: What is the process for conducting an experiment with this unit?
A: After preparing the chosen rod and water bath, users power on the heater and adjust the settings as required. Temperature at six points along the rod is tracked until desired data is collected, with cooling occurring naturally. All steps are monitored via a digital display and data logger.Q: What are the main benefits of using this heat transfer unit?
A: The main benefits include accurate and repeatable measurement of unsteady-state heat transfer, enhanced safety through thoughtful design, easy data collection, and suitability for a range of laboratory instructional and research activities. Its semi-automatic operation also promotes efficient, user-friendly experimentation.
