Electrical current flows through a cylindrical cable with a diameter of d = 4 mm generating thermal energy at a uniform rate of 1.6x107 W/m3. There is an insulation of t = 3 mm thickness with a conductivity of 0.2 W/mK. The system is exposed to convection as shown in the figure. Be careful, the outer diameter of the system with insulation becomes d + 2t. Calculate the surface temperature, Ts of the cable in °C.   Round your answer to the nearest integer value and write only the numerical value in the provided box, not the units.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
