A 2 ft by 2 ft square plate that weighs 25 lb slides down a long, inclined ramp. The plate is separated from the ramp by a layer of oil 0.0125 in. thick. The viscosity of the oil is 0.004 lb s / ft$^2$. Estimate the terminal velocity of the plate.

A flat plate that is 2 ft. x 1 ft. slides on oil (absolute viscosity = 0.018 # sec/ft²) over a large plan surface, as shown in the figure below. What force, F is required to drag the plate at a velocity of 6.5 feet per second if the thickness, t of the separating oil film is 0.025 inches? Plate Oil F t a. 112 pounds b. 207 pounds c. 346 pounds d. 622 pounds

A flat plate with surface area of 5 m^2 is sliding on a horizontal table with 3 mm thick oil layer on top. Force applied on the plate in the direction of movement is 5.8 N . Dynamic viscosity of the oil is 0.89 x10-3 Ns/m2. a) Calculate the terminal velocity of the plate.

(2)A square plate 50 cm X50 cm weighing 200 N slides down an inclined plane of slope 20° to the horizontal with a uniform velocity of 0.4 m/s: If thin layer of oil of thickness 0.5 cm fills the space between the plate and the inclined plane; determine the coefficient of viscosity of the oil.
