Is the Flow Laminar or Turbulent? Determining with Reynolds Number

[joe98]

Homework Statement

For the following situations of steady flow, determine whether the flow is laminar or
turbulent based on Reynolds number: water at 10oC flowing at an average velocity of
2 m/s in a 100-mm pipe, (Viscosity of water at 10oC: 1.31 cP, density: 1000 kg/m3)

Homework Equations

Re=ρVd/μ=vL/viscosity

The Attempt at a Solution

so Re=(1000x2x0.1)/(1.31x10^-3)=152671.8

therefore its turbulent flow

Am I correct in this method?

Yes but watch your significant figures.
