    Phy P5 confusions (mine & your's).

    s part? We are not taking units of s^-1 as we took log of it. @your 2nd post. You can use any, just remember, that if you do max-min then you have to divide by 2. If you do max-best, then don't divide by 2. That's it.

    Phy P5 confusions (mine & your's).

    June 2008: Units of η are simple, look. η = gradient/row now go back and see the units of gradient, that are m^-1 (do not include s^-1 as you took log of it) now put units in equation η = m^-1/kg m^-3 so, units of η = kg^-1 m^2 Hope that helps :)
