2) A thin 40-cm X 40-cm flat plate is pulled at
2 m/s horizontally through a 3.6 mm thick oil
layer sandwiched between two plates, as
shown in the figure. The dynamic viscosity of
oil is 0.027 Pa.s. Assuming the velocity profile
to be linear, (a) plot the velocity profile and
find the location where the oil velocity is zero
and (b) determine the force F needed to
maintain the motion.
