Determine the heat exchange per m² of area a, in the following cases if a, is at 1000 k and a, is at 400 k, both surfaces being black. (i) perpendicular planes 2 mx 1 m size with 2 m being the common edge (ii) perpendicular planes of 2 mx 1 with 1 m being the common edge. (ii) equal coaxial parallel disks of 1 m dia, placed 1 m apart (iii) same as in (iv) but placed 0.5 m apart. (v) concentric circular disks of 1 m dia and 0.5 m dia placed 0.5 m apart with the smaller one as surface a1
