Question

State various shapes factor algebraic relation in radiation heat transfer?

Answer 1

Answer:

make as brainliest

Explanation:

hope you understand it

There is a factor called the SHAPE FACTOR (Fij) OR view factor or configuration factor or form factor

or geometric factor which accounts for the orientation and geometry of the surfaces exchanging. Shape factor F12 = ratio of radiations intercepted by surface 2 / radiations leaving

surface 1. Its symbol is Fij. Say for example 140 units of energy emitted by body A. 35 units of

energy are received by a body B. Then FAB= 35/140=0.25. It depends how the surfaces view each

other and also how the surfaces radiate energy with respect to each other.
