A 6-m-long 2-kW electrical resistance wire is made of 0.2-cm-diameter stainless steel (? = 15.1 W/mK). The resistance wire operates in an environment at 30°C with a heat transfer coefficient of 140 W/m2 K at the outer surface. Determine the maximum temperature in the wire; (a) by using the applicable relations. (b) by setting up the proper differential equation and solving it.
