An infinite plate is moving at a constant velocity of 0.3m/s over a second stationary plate. A thin layer of the liquid with viscosity of 0.65 centipoises and specific gravity of 0.88 separates the moving plate from the stationary plate. The fluid velocity varies linearly with the distance from the stationary plate. If the length between the two plates is 0.3mm, determine: The absolute viscosity of the liquid in s                                                                          The kinematic viscosity of the liquid stokes The shear stress on the fluid layer

A plate of width 19 cm and length 49 cm is moved at a velocity of 0.07 m/s. The plate is separated from a surface moving in the opposite direction at 0.2 m/s by an oil filled gap of 0.13mm. If the oil has a viscosity of 0.25 Pa.s, determine the force required to move the plate relative to the moving surface. State your answer in N, correct to 2 d.p.

A sled with two runners slides along a thin horizontal layer of water between the ice and the runners. The horizontal force that the water puts on the runners is equal to 2.4 lb when the sled's speed is 50 ft/s. The total area of both runners in contact with the water is 0.04 ft2, and the viscosity of the water is 3.5x10 lbs/ft2. Determine the thickness of the water layer under the runners. Assume a linear velocity distribution in the water layer.

5Q. The plate is moving at 0.6 mm/s when the force applied to the plate is 4 mN. If the surface area of the plate in contact with the liquid is 0.5 m², determine the approximate viscosity of the liquid, assuming that the velocity distribution is linear. The thickness of the liquid layer is 4 mm. 0.6 mm/s 4 mm 4 mN
