2, Di % jDw or Di=Dw % j and Di @i ¼ ¼ j: Dw ! 0 Dw @w lim In the same way, it can be shown that @j=@w ¼ Ài. 2 Derivation of formulas @i=@w ¼ j and @j=@w ¼ Ài. 18) components pnt are satisfied equalities pwr ¼ prw ¼ pzr ¼ prz ¼ pwz ¼ pzw ¼ 0: Then, prr ; pww ; pzz are only normal stresses and, for example, prr could be considered as pressure Àp. It can be shown that other stresses are equal to Àp; that is, pww ¼ Àp; pzz ¼ Àp. 13) the common component Àp (in what follows it will be considered as only such media) can be separated, so the stress components take the form prr ¼ Àp þ trr ; prw ¼ trw ; pww ¼ Àp þ tww ; prz ¼ trz ; pwz ¼ twz : pzz ¼ Àp þ tzz ; ð4:2:15Þ It is able to prove that pwr ¼ prw , pzr ¼ prz , and pwz ¼ pzw .
Consider a flow of real medium between unbounded parallel surfaces. Let the upper surface of the channel between two plates (Fig. 5a) or coaxial cylinders (Fig. 5b) move with constant velocity w0, and the lower one is motionless. Sticking condition at the wall gives rise to stress t caused by friction resistance owing to sliding of medium layers moving with different velocities w. 5 Scheme of velocity distribution in a gap in laminar flow induced by the motion of upper plate (a) and internal cylinder (b).
