Question: A solid truncated cone has a circular cross section, and its diameter is related to the axial coordinate by an expression of the form D=ax

A solid truncated cone has a circular cross section, and its diameter is related to the axial coordinate by an expression of the form D=ax^3/2. where a = 0.9 m^-1/2. The sides are well insulated, while the upper surface of the cone at x₁ is held at T₁ and the lower surface at x₂ is held at T₂.

Determine the thermal resistance, in K/W, of the truncated cone made of copper (k = 385 W/mK) when x₁ = 98 mm, T₁ = 108C, x₂ = 212 mm, and T₂ = 13C.
