Evaluate the appropriate mean area for steady-state heat conduction in a hollow sphere that satisfies an equation

Question:

Evaluate the appropriate €œmean€ area for steady-state heat conduction in a hollow sphere that satisfies an equation of the form

Repeat part (b) of Problem 17.2 for the spherical case.

Data From Problem 17.2 Part(b)

If the arithmetic mean area, Ï€ (r_o - r_i), is used rather than the logarithmic mean, calculate the resulting percent error for values of r_o/r_i of 1.5, 3, and 5.
