If the surface of a plane wall with heat conduction coefficient k is under constant heat flux (q0 ") condition at x = 0 and its surface at x = L is at temperature Ts, which of the following is the temperature distribution of this plane wall?
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.
Given:
Plate thickness: 30 mm
