1-
2-
3-
4-
2.4.1 What is the meaning of q?
2.4.2 Compare and contrast at least three of the various fins in Figure 2. 20.are the key differences with respect to heat transfer effectiveness?
2.6 What variable do we now need to consider in transient conduction?
2.6.1
a) Explain the physical meaning of the Biot Number.
b) Explain the physical meaning for the terms in equation 2.87.
1.
c) What assumptions are necessary to use equation 2.90?
2.6.2 With respect to heat transfer, what is unique about an infinite slab?
2.6.3 With respect to heat transfer, what is unique about a semi-infinite solid?
2.7 When can we use the charts for transient heat conduction?
Explanation / Answer
heat transfer rate can be increased by increasing surface area,, through introducing fin we make the surface area large to increase the heat transfer ... i know this part ,, may be useful for you.
