Black Body Radiation: Determination of Stefan's Constant
.
.

 

Assignments:

 

  1. Find the steady state temperature of  the black body disc having radius 2cm and mass 7g  at 450C surrounding temperature, when kept initially at 280C. Hence determine Stefan's constant.
  2. Determine the net heat transfer through the black body disc with radius 4cm and mass 9g, at 320C when transferred to a surrounding temperature of  650C.
  3. Find the steady state temperature of  the black body disc having radius 3cm and mass 5g  at 10 0C surrounding temperature,when kept initially at -10 0C.
  4. Determine the net heat transfer through the black body disc with radius1cm and mass 6g,  at 00C when  transferred to a surrounding temperature of 100C.
  5. Determine the net heat radiated by the black body disc of mass 6g and radius 4cm at  400C,initially kept at 300C.
