The velocity difference between two adjacent layers of liquid with a thickness of dn = 0.02 mm is equal to du = 0.0072 m/h. The liquid in question has a dynamic viscosity coefficient? = 13.04•10-4 N•s/m2. Determine the tangential stress and friction force per 1 m2 of surface between layers of liquid (Fig.).
