The space between two square flat parallel plates is filled with oil. Each side of the plate is 60cm. the thickness of the oil film is 12.5mm, the upper plate, which moves at 2.5 m/s requires a force of 98.1N to maintain the speed. Determine a) the dynamic viscosity in poise, b) the kinematic viscosity of the oil in stokes if the specific gravity of the oil is 0.95.

The space between two square parallel plates is filled with oil. Each side of the plate is 720 mm. The thickness of the oil film is 15 mm. The upper plate, which moves at 3 m/s requires a force of 120 N to maintain the speed. Determine: (i) the dynamic viscosity of the oil. (ii) the kinematic viscosity of oil if the specific gravity of oil is 0.95.

Oil (absolute viscosity $=0.0003 \mathrm{lb} \cdot \mathrm{s} / \mathrm{ft}^{2}$, density $=50$ Ibm/ft' $^{3}$ flows in the boundary layer, as shown in Fig. P1.82. The plate is $1 \mathrm{ft}$ wide perpendicular to the paper. Calculate the shear stress at the plate surface.
