As seen in the figure, a composite wall consists of three different materials (Material Material-B, and Material-C). Fluid temperature on the left side of the wall is T=758 with a heat transfer coefficient of h=48 W/(m2°C). Calculate the temperature drop across Material-B (TB,1- TB,2) under steady state conditions by considering the material properties given below.

Heat transfer
As seen in the figure, a composite wall consists of three different materials (Material-A,
Material-B, and Material-C). Fluid temperature on the left side of the wall is T=758°C
with a heat transfer coefficient of h=48 W/(m2°C). Calculate the temperature drop
across Material-B (TB,1 - TB,2) under steady state conditions by considering the
material properties given below.
Material-A: Thickness a=30 cm, thermal conductivity kA=23 W/(m°C), surface
temperature on the left side is T;=553°C.
Material-B: Thickness b=30 cm, thermal conductivity kg is unknown.
Material-C: Thickness c=13 cm, thermal conductivity kc=57 W/(m°C), surface
temperature on the right side is T,-27°C.
