The top of
12 he top of a 3/16 inch thick acrylic testing box is covered with an unknown
chinsulation material (black). the dimensions of box are 10 inch x 10 inch on
e. the sides and are wrapped with a control insulting material (blue) so that
me almost all heat loss is through the 10 inch x 10 inch unknown insulating material
h e top of the box (assume no heat is lost from the bottom or sides of the box).
determine the thermal conductivity for the insulating material if a 25 w bulb is used
to heat the box. you may assume the only heat loss from the box occurs through the
10 x 10 test area. the bulb maintains the inside temperature at 10 °c higher than the
outside temperature.
