Thermal radiation and heat transfer are fundamental concepts in physics, engineering, and material science. Understanding the principles of radiation helps researchers and students measure energy transfer, study emissivity, and validate theoretical laws. The Stefan Boltzmann’s Apparatus, available at Scilabex.com and Scilabstore, is designed to determine the Stefan-Boltzmann constant and explore the relationship between temperature and radiative energy. This laboratory apparatus is suitable for academic institutions, research centers, and industrial labs, with PAN India and international delivery.

Product Overview

The Stefan Boltzmann’s Apparatus is a precision laboratory instrument that allows experimental verification of the Stefan-Boltzmann law. It consists of a hemisphere mounted on a Bakelite plate, which forms a jacket for heating. Hot water from a tank above the hemisphere heats it uniformly, and a copper test disc is placed at the center of the hemisphere.

Key features include:

• Hemisphere and Bakelite Plate: Ensures uniform heating of the apparatus.

• Hot Water Tank: Provides controlled heating to the hemisphere.

• Copper Test Disc: Acts as the sample for measuring radiation effects.

• Temperature Sensors: Measure temperatures of the hemisphere and the test disc accurately.

• Durable Metal Construction: Ensures long-lasting laboratory use.

• Voltage: Operates at 220 V for laboratory convenience.

This setup allows students and researchers to measure the Stefan-Boltzmann constant and study how temperature affects radiant energy, providing hands-on understanding of radiative heat transfer.

Working Principle

The Stefan Boltzmann’s Apparatus is designed based on the Stefan-Boltzmann law, which states that the total radiant energy emitted by a black body is proportional to the fourth power of its absolute temperature.

1. Hemisphere Heating: The hemisphere is heated using hot water supplied from the tank mounted above.

2. Test Disc Placement: A copper test disc is placed at the center of the hemisphere for radiation measurement.

3. Temperature Measurement: Temperature sensors monitor the hemisphere and test disc temperatures.

4. Data Analysis: The heat emitted by the test disc is measured and related to the hemisphere temperature to determine the Stefan-Boltzmann constant.

5. Temperature Variation Studies: The effect of changing hemisphere temperature on radiation is analyzed, allowing for comprehensive learning about radiative heat transfer.

This apparatus allows controlled, precise, and reproducible measurements, essential for educational, research, and industrial experiments.
