Darcy equation, hydraulic conductivity calculation

  1. Jan 17, 2010 #1
    1. The problem statement, all variables and given/known data
    ive done the darcy experiment in the lab already and have the data, the question asks to calculate the hydraulic conductivity,K. ive done one already and im just looking for confirmation that ive done it correctly because ive never used this equation before. I know im finding K.


    2. Relevant equations
    darcy equation Q=KiA


    3. The attempt at a solution
    so one set of data that i have is:
    dl= 0.418 m
    volume= 14 mL
    time= 10 seconds
    dh= 0.34 m
    diameter of cylinder is 6.3 cm

    and heres what ive done with it.
    K=Q/iA
    = 1.4mL/s / (0.81)(31.17cm^2)
    = 0.055

    as i said im not really sure if ive done this correctly because ive never used darcy's equation. also could someone also help me out with the units please?
