Description and Specification for Lab Tenders
STEFAN BOLTZMANN APPARATUS.
DESCRIPTION:
The unit consists
of a hemisphere surrounded by hot water. The instrument determines
Stefan Boltzmann constant. Water heating tank is provided to supply hot
water. Stefan Boltzmann constant is determined from the temperature
raise rate when blacked disc is inserted at the centre of disc from
hemisphere by radiation & its temperature begins to rise.
SPECIFICATION:-
• Hemisphere dia. - 0.205 m.
• Base Bakelite plate - 0.05 m.
• Test disc dia. - 0.0195 m.
• Thickness of test disc - 0.003 m.
• Thermocouples on hemisphere - 4 Nos.
• Water tank of capacity with immersion heater. - 8 litre
• Thermocouple on test disc - 1 No.
• Temperature indicator. - 0-300 oC
FEATURES:-
• The phenomenon of heat transfer by radiation can be understood well.
• Stefan Boltzmann constant can be calculated.
• Easy to operate.
• Ideal for group studies and demonstration.
