The ends of a copper rod of length 1m and area of cross-section 1cm^2 are maintained at 0 degree celcius and 100 degree celcius. At the centre of the rod there is a source of heat of power 25W. Calculate the temperature gradient in the two halves of the rod in steady state. Thermal conductivity of copper is 400 W/m/K.

Dear Arnab,

Consider the rod to be divided into two equal parts and then evaluate steady state temperature gradient. Then add the two parts to get the desired answer.

?Best Of Luck...!!!!
