Determine the allowable maximum temperature of the rubber


Determine the allowable current in a 10 gage (2.59 mm diameter) copper wire that is insulated with a 1 cm - O.D. layer of rubber. The outside heat transfer coefficient is 20 W/m^2K, and the ambient air is at 310 K. The allowable maximum temperature of the rubber is 380 K. Take k=0.15 W/mK for the rubber and an electrical resistance of 0.00328 ohms/m for the copper wire.
