Reynolds number question

  1. Mar 14, 2012 #1
    1. The problem statement, all variables and given/known data

    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)

    2. Relevant equations

    Re=ρVd/μ=vL/viscosity

    3. 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.
