For steady-state conditions, deni d an equation for the velocity of the lower plate.

Oil: u2 S = 0.9 PROBLEM 9.11

Explanation / Answer

9.10 (a) False: There is two plate upper plate is moving with velocity U and lower plate is fixed ( zero velocity)

So Velocity at top is U and at bottom is Zero

(b) False: Maximum Shear occure at minimum velocity in Middle velocity is hiegher so shear stress is less

( c) True: as next to the boundary velocity is zero so max shear

(d) False: There is shear stress at the plate so its mean fluid is viscous or fluid have certain viscosty so it false for irrotational flow fluid must have zero viscosity

(e) True: as the fluid has viscosty so rotational
