Answer to Question #242965 in Physics for Kunal Dahre

Question

Find the kinematic viscosity of an oil having density 980kg/m^2 when at a certain point in the oil the shear stress is 0.25N/m^2 the velocity gradient is 0.3 pre sec

Answer 1

The kinematic viscosity is

$$\nu=\frac{\tau}{\rho(\Delta v/\Delta h)}=\frac{0.25}{980(0.3)}=8.5\text{ St}.$$
