1. If the dynamic viscosity of water at 20-C is 1 E-3 N-s/m, what is the kinematic viscosity in the English units? 2. The kinematic viscosity of 1 ft/s is equivalent to how many stokes? 3. A 15 kg block slides down a 25-degree inclined plane on a 0.2-mm-thick film of SAE 30 oil gap at a temperature of 60-F. If the contact area is 0.15 m, find the terminal velocity of the block, assuming a linear velocity distribution in the gap. 4. A flat plate 60 cm x 120 cm slide on SAE 10 oil with a viscosity = 1.04 E- 1 Pa-s, over a large plane surface. What force is required to drag the plate at 3.5 m/s if the oil film is 3 mm thick? (Ans. F = 87.36 N)
