## Homework Statement

I need to find the pipe diameter or mean velocity.

Q= 0.01m^3s

Density= 960kg m^3

Viscosity = 0.081 Pa s

Max Velocity = 1.8 m s

## Homework Equations

Mean velocity= 4Q/pi.D^2

## The Attempt at a Solution

I have two unknowns in this equation so I'm unable to find D or Mean Velocity. Am I right in thinking the mean velocity is max velocity/2? And does this work for laminar/Turbulent/transitional flow? Any help appreciated. Thanks
