Answer
Assume that you have an aluminum rod that has a diameter of 2.0 cm. One end is kept at 460 degrees C and the other is immersed in water at 22 degrees C. What is the heat conduction rate along the rod?
From the table we obtain k: 200 J/smC
The crosss-sectional area, A, is found to be pr2 = (3.1416)(1.0x10-2 m)2
Q/t = kA((T1 - T2)/l =
