The both ends of a 6 mm diameter copper rod (U — shaped) having k = 330 W/mK are rigidly connected to a vertical wall as shown in the figure. The wall temperature is constant at 110°C. The developed length of the rod is 50 cm and is exposed to air at 30°C. The value of h = 30 W/m2K. Find: (i) temperature at centre of the rod, and (ii) heat transfer by the rod.
