Two large horizontal plane surfaces are 2 cm apart. The space between the surfaces is filled with the fluid of dynamic viscosity of 8 Poise. What will be the force required to drag a very thin plate of surface area 1 m2 between the two large plane surface with a speed of 0.5 m/s. The thin plate equidistance of 1 cm from each large plane surface. Buoyancy and gravitational effects are considered to be negligible.

1.	Two large horizontal plane surfaces are 2 cm apart. The space between the surfaces is filled with the fluid of dynamic viscosity of 8 Poise. What will be the force required to drag a very thin plate of surface area 1 m2 between the two large plane surface with a speed of 0.5 m/s. The thin plate equidistance of 1 cm from each large plane surface. Buoyancy and gravitational effects are considered to be negligible.
