A4 mm-diameter electrical wire is insulated by a 3 mm-thick rubberized sheath (k = 0.15 w/m·k), and the wire/sheath interface is characterized by a thermal contact resistance of 4 × 10−4 m2 ·k/w. the convection heat transfer coefficient at the outer me 3371, fall 2019, simmons page 1 of 2 surface of the sheath is 20 w/m2 ·k, and the temperature of the ambient air is 22◦c. if the temperature of the insulation may not exceed 60◦c, what is the maximum allowable electrical power that may be dissipated per unit length of the conductor? what is the critical radius of the insulation?
