Textbook Question
Chapter 8.15, Problem 1KCP
Define (a) a phase in a material and (b) a phase diagram.
(a)
Expert Solution
To determine
A phase in a material.
Explanation of Solution
Phase refers to the physical similarity and difference among the regions of a material. Phase in a material is a portion or area that contrasts in its microstructure and composition from another portion or area of the same material.
(b)
Expert Solution
To determine
A phase diagram.
Explanation of Solution
A phase diagram refers to the graphical or pictorial representation of various phases exists in a material system at different temperatures, pressures, structures and compositions. It is constructed by using conditions of equilibrium. Large number of phase diagrams constructed in temperature versus composition plot.

A program to make the part depicted in Figure 26.A has been created, presented in figure 26.B, but some information still needs to be filled in. Compute the tool locations, depths, and other missing information to present a completed program. (Hint: You may have to look up geometry for the center drill and standard 0.5000 in twist drill to know the required depth to drill).
We consider a laminar flow induced by an impulsively started infinite flat
plate. The y-axis is normal to the plate. The x- and z-axes form a plane parallel
to the plate. The plate is defined by y = 0. For time t <0, the plate and the flow
are at rest. For t≥0, the velocity of the plate is parallel to the 2-coordinate;
its value is constant and equal to uw. At infinity, the flow is at rest. The flow
induced by the motion of the plate is independent of z.
(a) From the continuity equation, show that v=0 everywhere in the flow and
the resulting momentum equation is
მu
Ət
Note that this equation has the form of a diffusion equation (the same form as
the heat equation).
(b) We introduce the new variables T, Y and U such that
T=kt, Y=k/2y, U = u
where k is an arbitrary constant. In the new system of variables, the solution
is U(Y,T). The solution U(Y,T) is expressed by a function of Y and T and the
solution u(y, t) is expressed by a function of y and t. Show that the functions are
identical.…
