Poiseuille Flow

  1. Feb 4, 2010 #1
    1. The problem statement, all variables and given/known data
    A container filled up over 60 seconds.


    The following results are given:
    Height (metres) | Flow Rate (cm^3 s^-1)

    0.1 2.0
    0.2 4.1
    0.3 5.8
    0.4 7.9
    0.5 9.8

    Using this data plot a graph of flow rate (vertical axes) against height (horizontal) and hence calculate the viscosity of water.

    2. Relevant equations

    N/A?



    3. The attempt at a solution

    I plotted the graph and got the gradient as 1.97 x 10^-5 however I don't know how to calculate the viscosity from here.
