Question
An oil is flowing between two parallel horizontal plates which are 20 mm apart. The top plate is moving with
a uniform speed 0.1 m/s. The viscosity of the oil is 0.1 N s/m2
. The velocity at the centerline is 1.95 m/s.
Consider the flow to be a fully developed one.
a) Derive the velocity profile
b) Calculate pressure difference between two points (P1-P2) 5 m apart
c) Find the velocity at 3 mm from the wall of the bottom plates.
d) Find the velocity at 3 mm from the wall of the top plates.
e) Determine force acting on the bottom wall, (W=10 cm)
