7. In a catalyst bed packed in the annular space of two coaxial cylinders of diameter 2.5 cm and 3.5 cm respectively a chemical reaction is carried generating a heat at 500000 W/m3 uniformly throughout the annular volume. The inner wall has uniform surface temperature of 450 C. What is the surface temperature of the outer wall if heat is assumed to be flowing radially outward and system is at steady state. (hint: consider 1D heat equation with heat generation term for cyclinder, integrate and use boundary conditions to solve)
