Part 3: Unswer the following (5Marks) 1) Find the kinematic viscosity of an oil having density 981 kg/m3 and shear 5 stress at a point in oil is 0.2452 N/m. The velocity gradient at that point is 0.2 per sec. 2) Show that the streamlines and path lines are the same in the flow field described by XL V = 1+t
