solution :-
A copper rod is 5 mm in diameter and 100 mm in length; one end of the rod is maintained at 100°C . The surface of the rod is exposed to ambient air at a temperature of Ta = 25°C with a convection heat transfer coefficient of 100 W/m2s. The thermal conductivity of copper is 398 W/m K.
This problem can be solved as:
a) It can be solved as lumped or distributed
b) Distributed system
c) Lumped system
d) Non of the answers are correct
