Stefan Boltzman Apparatus

Stefan Boltzman Apparatus 

• The apparatus is designed to determine the Stefan Boltzman constant.
• The apparatus consists of a hemisphere fixed to a Bakelite plate, the outer surface of which forms the jacket to heat it.
• Hot water to heat the hemisphere is obtained form a hot water tank, which is fixed above the hemisphere. The copper test disc is introduced at the center of hemisphere.
• The temperatures of hemisphere and test disc are measured with the help of temperature sensors.

Experimentation:

• Determination of Stefan Boltzmann constant and study the effect of hemisphere temperature on it.

Utilities Required:

• Electricity Supply : 1 Phase, 220 V AC, 2 kW.
• Table for set-up support.

Technical Specifications:

• Hemisphere Dia: 200 mm (approx.) made of Copper
• Jacket Dia: 250 mm (approx.) made of Stainless Steel
• Test Disc Size: 20 mm Dia. x 1.5-mm thickness made of Copper
• Water Tank: Stainless steel 12 Ltrs. cap
