The conductivity of an 85% magnesia insulating material is given by k(T) = C0 + C1 T for 100°F ≤ T ≤ 300°F. Determine the rate of heat flow q between these temperatures for a slab of thickness t. Figure 93.1 Conductivity Problem Sketch Material Properties
C0 = 0.031 Btu/hr-ft-°F Geometric Properties
t = 3 in = 0.25 ft C1 = 0.000031 Btu/hr-ft-°F2 Loading
T1 = 300°F
T2 = 100°F Analysis Assumptions and Modeling Notes
A 1 ft2 area is used for the conduction element. Results Comparison
