A copper bar of thermal conductivity 401 W/(mK) has one end at 104C and the other end
Question:
A copper bar of thermal conductivity 401 W/(m·K) has one end at 104°C and the other end at 24°C. The length of the bar is 0.10 m, and the cross-sectional area is 1.0 × 10−6 m2.
(a) What is the rate of heat conduction along the bar?
(b) What is the temperature gradient in the bar?
(c) If two such bars were placed in series (end to end) between the same constant-temperature baths, what would be?
(d) If two such bars were placed in parallel (side by side) with the ends in the same temperature baths, what would be?
(e) In the series case, what is the temperature at the junction where the bars meet?
