why is a water stream streamline whn it is ejected with an optium speed but it becomes turbulent when the speed of ejection of water is increased ?

Expert Answer:

Dear student
R= Vc ρ D / η
Reynold's number 'R' is a pure number and therefore, its numerical value is same in every set of units. The flow of viscous liquid is said to be steady when R lies between 0 and 2000. For values of R about 3000 floe is turbulent. For R lying between 2000 and 3000, the flow is unstable and may switch over from one type to another.
We hope this clarifies your doubt.
