Water is flowing in a pipe of radius 1.5...

Water is flowing in a pipe of radius 1.5 cm with an average velocity 15 cm `s^(-1)`. What is the nature of flow? Given coefficient of viscosity of water is `10^(-3)` kg `m^(-1) s^(-1)` and its density is `10^(3)` kg `m^(-3)`

A

Streamline

B

Turbulent

C

Unstable

D

Critical

Text Solution

Verified by Experts

The correct Answer is:
C
Diameter D=3`xx10^(-2)m`
Reynold number `N_R=(rhovD)/(eta)`
`=(10^3xx0.15xx3xx10^(-2))/(10^(-3))`
`:." "N_R=4500`
As `N_Rgt3000`, the flow of turbulent.
