Answer: 0.471 m/s
Explanation:
We are given the followin equation:
(1)
Where:
is the Reynolds Number, which is adimensional and indicates if the flow is laminar or turbulent
When we have a laminar flow
When we have a turbulent flow
When the flow is in the transition region
is the diameter of the pipe. If the pipe ha a radius its diameter is
is the average speed of the fluid
is the density of the fluid
is the viscosity of the fluid
Isolating :
(2)
Solving for
(3)
Finally:
