Question

 Consider an illustration of two parallel plates with fluid in between, as shown in the
figure below.
(a)  How much shear stress, in pascals (Pa), is required to slide the top plate at a
velocity of V = 1 m/s (keeping the bottom plate fixed) if the fluid is glycerol at 21 o
C, and
the width of the gap, “h” is 1 mm?
(b) What is the tangential force, in Newtons (N), required if the top plate is a 2-inch
by 2-inch square?
