Question: explain step by step 16-44 A 2.1-m-long, 0.2-cm-diameter electrical wire extends across a room that is maintained at 20C. Heat is generated in the wire

explain step by step

16-44 A 2.1-m-long, 0.2-cm-diameter electrical wire extends across a room that is maintained at 20C. Heat is generated in the wire as a result of resistance heating, and the surface temperature of the wire is measured to be 180C in steady operation. Also, the voltage drop and electric current through the wire are measured to be 110V and 3A, respectively. Disregarding any heat transfer by radiation, determine the convection heat transfer coefficient for heat transfer between the outer surface of the wire and the air in the room. Answer: 156W/m2K
