CH E 314 Heat Transfer ASSIGNMENT 3 Sample Solution
Consider a plane wall in which heat is generated at a uniform rate.
The steady state temperature profile is given by the following
a + b x2
Where a = 200C and b = -2000C/m2. The th

Problem # 2
Consider a freezer with a cubic cavity of inside dimension 2 m a side. The bottom is perfectly
insulated (no heat transfer). The material of the top and sides has a thermal conductivity of 0.03
W/m K. When t
