Assignments:
- 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.
- 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.
- 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.
- 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.
- Determine the net heat radiated by the black body disc of mass 6g and radius 4cm at 400C,initially kept at 300C.
