Oil is filled within a tall cylindrical tank. A flat disk with a height of 1 cm and with a diameter of 5 cm is placed into the oil. There occurs a narrow spacing of 0.1 mm between the disk and the tank wall. Due to the forces acting on the disk, it moves downward, and after some time, the speed of the disk reaches a terminal velocity. Beyond this moment, measurements reveal that the disk moves 30 cm in 4 seconds. If the oil density is 600 kg/m3and the specific gravity of the disk is 1.5, determine the oil’s viscosity

Oil is filled within a tall cylindrical tank. A flat disk with a height of 1 cm and with a diameter of 5 cm is placed into the oil. There occurs a narrow spacing of 0.1 mm between the disk and the tank wall. Due to the forces acting on the disk, it moves downward, and after some time, the speed of the disk reaches a terminal velocity. Beyond this moment, measurements reveal that the disk moves 30 cm in 4 seconds. If the oil density is 600 kg/m3and the specific gravity of the disk is 1.5, determine the oil’s viscosity.
