A hot wire at a uniform temperature of 40°C and diameter, D= (10+x) mm where x-last two digits of your registration no, is coated with insulating material of thermal conductivity, k-0.1 W/m K with a thickness of 1 cm that is in perfect contact with the wire. The surrounding air is at 15°C and has a heat transfer coefficient of h=20 W/m K. How much heat is dissipated per meter of the wire at steady state? x=38 A hot wire at a uniform temperature of 40°C and diameter, D= (10+x) mm where x-last two digits of your registration no, is coated with insulating material of thermal conductivity, k-0.1 W/m K with a thickness of 1 cm that is in perfect contact with the wire.
