Answer to Problem 9.1P

  N/m2=66661.33

Explanation of Solution

Given:

500 mm Hg abs

Calculation:

1 mm Hg is 133.322387415m Pascal

mm Hg to newton per meter square formula is:

  N/m2=mmHg0.0075006N/m2=5000.0075006

  N/m2=66661.33

Answer to Problem 9.1P

  720torr=95992.12N/m2

Explanation of Solution

Given:

720 torr

Calculation:

1 torr is defined as 1/760 atm

Or 1 torr is 101325/760 pascals

  N/m2=torr0.0075006N/m2=torr×133.3224N/m2=720×133.3224N/m2=95992.12

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.…
