SPECIFICATION

Introduction:

The apparatus is designed to determine the Stefan Boltzmann 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 from 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.

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.

Heater: Nichrome wire immersion heater.

Control panel 0 0 comprising of Digital Temp.

Controller: 0 to 199.9 C

Digital Temp. Indicator: 0 to 199.9 C, with multi channel switch

Temperature sensors: RTD PT-100 type.
