A 35-mm length of 1-mm-diameter nichrome (80% Ni, 20% Cr) wire is heated to 915 K by the passage of an electrical current through the wire (Joule heating). The wire is in an enclosure, the walls of which are maintained at 300 K. Warm air at 325 K flows slowly through the enclosure. The emissivity of the wire is 0.5 and the convective heat-transfer coefficient has a value of 54.9W/m² · K. Determine the heat-transfer rate from the nichrome wire.
