A heat flux of 4000/J is to be passed through a copper rod of length 10cm and area of cross section 100sq. cm. The thermal conductivity of copper is 400W/mC . The two ends of his rods must be kept ta temperature difference of?
Dear student,
Using dQ/dt = KA∆T/l
we get ∆T = l/(K x A) x dQ/dt = 0.1/(400 x 100 x 10-4) x 4000 = 100oC
Hope this helps you.
Regards.
