Consider steady fully-developed incompressible flow of a Newtonian fluid between two infinite parallel flat plates. The plates move in the opposite directions, as shown in the figure. In the absence of body force and pressure gradient, the ratio of shear stress at the top surface (π¦= π») to that at the bottom surface (π¦= 0) is
- A. 1
- B. π1 π2
- C. π1 βπ2 π2
- D. π1 + π2 π2
Answer: A. 1
