A long copper tube (O.D.=0.5 m and I.D.=0.45 m) is centered in a concrete block (square cross-section having sides of 1 meter). Inside the tube there is a flow of air (average convective transfer coefficient h_air and T_air>T_s), while the sides of the block are kept at T_s=25 °C. The system is in steady state, the object is isotropic, and there is not heat generation inside the body. Assume the radiation effects to be negligible. Please answer the following questions: Sketch the thermal circuit, including all the thermal resistances and the temperatures at the nodes. Write the symbolic equation for each resistive term
