Poiseuille's law remains valid as long as the fluid flow is laminar. For sufficiently high speed, however, the flow becomes turb

Ilia_Sergeevich [38]

Answer: 0.471 m/s

Explanation:

We are given the followin equation:

$Re=\frac{D v \rho}{\eta}$ (1)

Where:

$Re$ is the Reynolds Number, which is adimensional and indicates if the flow is laminar or turbulent

When $Re$ we have a laminar flow

When $Re>4000$ we have a turbulent flow

When $2100$ the flow is in the transition region

$D=2R$ is the diameter of the pipe. If the pipe ha a radius $R=8(10)^{-3} m$ its diameter is $D=2(8(10)^{-3} m)=0.016 m$

$v$ is the average speed of the fluid

$\rho=1060 kg/m^{3}$ is the density of the fluid

$\eta=4(10)^{-3} Pa.s$ is the viscosity of the fluid

Isolating $v$ :

$v=\frac{Re \eta}{D \rho}$ (2)

Solving for $Re=2000$

$v=\frac{(2000)(4(10)^{-3} Pa.s)}{(0.016 m)(1060 kg/m^{3})}$ (3)

Finally:

$v=0.471 m/s$
