Consider a horizontal, D1-mm-diameter platinumwire
Chapter 10, Problem 10.32(choose chapter or problem)
Consider a horizontal, D?1-mm-diameter platinumwire suspended in saturated water at atmosphericpressure. The wire is heated by an electrical current.Determine the heat flux from the wire at the instantwhen the surface of the wire reaches its melting point.Determine the corresponding centerline temperatureof the wire. Due to oxidation at very high tempera-ture, the wire emissivity is ??0.80 when it burns out.The water vapor properties at the film temperature of1209 K are ?v?0.189 kg/m3, cp,v?2404 J/kg?K,?v?23? 0?6m2/s, kv? .113 W/m?K
