Viscosity can delay the onset of turbulence in fluid flow; that is, it tends to stabilize the flow. Consider syrup and water, for example, and make this plausible.

It is known that the flow of fluid is laminar at low speed and becomes disordered and irregular at sufficiently high speed. If the viscous friction produced due to the viscosity of the fluid is large, then the fluid is likely to be steady and laminar.
Water has less viscosity than the syrup. So, the flow of water is likely to produce turbulent sooner than the more viscous syrup. Thus, the mixing of both the water and syrup will make a mixture such that it becomes somewhat a viscous liquid in between water and syrup. This will delay the onset of turbulent in fluid flow.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.

An object of mass m = 0.25 kg oscillates in a fluid at the end of a vertical spring of spring
constant kH = 85 N/m, see Fig.1. The effect of the fluid resistance is governed by the
damping constant b = 0.07kg/s.
(i) Find the period of the damped oscillation.
(ii) By what percentage does the amplitude of the oscillation decrease in each cycle?
