Water is flowing in a pipe of radius

1 {~cm}

with an average velocity

20 {~cm} / {s}

. If coefficient of viscosity of water is

10^{-3} {~kg} {~m}^{-1} {~s}^{-1}

and density is

10^3 {~kg} / {m}^3

, then the nature of flow is

View answer and explanation

Correct option: A

Turbulent

Option A (Turbulent) is correct because the calculated Reynolds number (4000) exceeds the critical value, indicating turbulent flow.
