1)Write the one-dimensional heat diffusion equation with thermalgeneration per unit volume and constant properties, assumingunsteady heat transfer.
2)
Consider two identical pin fins, however one of the pin fins hasa diameter which is 2X larger than the other. Comment on the effectthis may or may not have in terms of efficiency andeffectiveness.
Now consider two plate fins which are identical, however one is2X thicker, How does this effect the efficient andeffectiveness?
