Question: A ceramic has ko = 0.65 W / m-K. If this ceramic is shaped into a cylinder with a porosity distribution of P = 0.1(x

A ceramic has ko = 0.65 W / m-K. If this ceramic is shaped into a cylinder with a porosity of P = 0.1(x / L) (l - x / L), where x is the distance from one end of the cylinder and L is the total cylinder length, estimate the average thermal conductivity of the cylinder?
