A copper wire, 0.8-mm OD, 5 cm long, is placed in an air stream whose temperature rises
Question:
A copper wire, 0.8-mm OD, 5 cm long, is placed in an air stream whose temperature rises at a rate given by Tair = (10 + 14t) °C, where t is the time in seconds. If the initial temperature of the wire is 10°C, determine its temperature after 2 s, 10 s, and 1 min. The heat transfer coefficient between the air and the wire is 40 W/(m2 K).
