Dimensional Analysis, Two Engineering Equations

  1. Feb 6, 2012 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    n/a


    3. The attempt at a solution
    Conversions from EE units to CGS units:
    Code (Text):
    psi -> g/cm*s^2                  = 68948
    lb/gal -> g/cm*s^3               = 0.1198
    in -> cm                         = 2.54
    ft/sec -> cm/s                   = 30.48
    ft -> cm                         = 30.48
    cp -> g/cm*s                     = 0.01
    I ended up getting 3.5*10^-9 but I am not sure about this answer.

    3. The attempt at a solution
    For this one I ended up getting
    ΔPf = [itex]\mu[/itex]pLv / (1.2x10^-3)(d0-di)^2 + YbL / (.065)(d0-di)
    again, not sure about this conversion constant.

    Any help would be appreciated.
