Derive the heat equation for a homogeneous one-dimensional rod with a non-constant crosssection of area A(x) and perimeter P(x). Suppose that the lateral surface is not insulated and the amount of heat energy leaving the rod via the lateral surface per unit area per unit time is proportional to the difference of the temperature in the rod and the temperature w(x, t) of the air surrounding the rod (use the coefficient of proportionality α). Furthermore, suppose that there are no heat sources.

A homogeneous three-dimensional solid has a heat capacity at constant volume CV that depends on temperature T. Neglecting differences in the transverse and longitudinal waves in the solid, there are 3N vibrational modes, where N is the number of atoms in the solid. Here, the solid has N = 3.01 x 1023 atoms which occupy a total volume V = 18.0 cm3 . There are two transverse shear waves and one longitudinal wave; all waves have the same speed of...

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