Determine the kinematic viscosity (Stokes) of oil having the relative density as 0.85. The shear stress at a point in oil is 1.01 N/m and the velocity gradient at that point is 0.32 per second. Solution: (1) Viscosity (in Ns/m?) = (ii) Dynamic Viscosity (in poise) = (iii) Mass density of oil (in kg/m3) = iv) Kinematic viscosity (in stokes) =
