The space between two square flat parallel plates is filled with oil. Each side of the plate is 540 mm. the thickness of the oil film is 8 mm, the upper plate, which moves at 2.6 m/s requires a force of 90 N to maintain the speed. Determine a) the dynamic viscosity of oil in poise, b) the kinematic viscosity of the oil in stokes if the specific gravity of the oil is 0.8. And also draw the neat sketch.

The space between two square flat parallel
plates is filled with oil. Each side of the plate
is 540 mm. the thickness of the oil film is 8
mm, the upper plate, which moves at 2.6
m/s requires a force of 90 N to maintain the
speed. Determine a) the dynamic viscosity
of oil in poise, b) the kinematic viscosity of
the oil in stokes if the specific gravity of the
oil is 0.8. And also draw the neat sketch.
