Determine by means of a flux plot the temperatures and heat flow per unit depth in the ribbed insulation shown in the accompanying sketch.
GIVEN
The sketch below
FIND
(a) The temperatures
(b) The heat flow per unit depth
ASSUMPTIONS
Steady state conditions
Two dimensional heat flow
The heat loss through the insulation is negligible
The thermal conductivity of the material is uniform
SKETCH
The total number of heat flow lanes (M) = 11
The number of curvilinear squares per lane (N) = 8
Therefore, the shape factor is
The rate of heat transfer for unit depth is given is
