A 2.1-m long, 0.2-cm diameter electrical wire extends across a room that is maintained at 20°C. Heat is generated in the wire as a result of resistance heating, and the surface temperature of the wire is measured to be 180°C in steady operation. Also, the voltage drop and electric current through the wire are 110 V and 3 A, respectively. Disregarding any heat transfer by radiation; determine the convection heat transfer coefficient for heat transfer between the outer surfaces of the wire and the air in the room.
