McqOptions · Answer

$\frac{\phi_c-\phi_w}{\phi_E-\phi_w} = \frac{1}{2}(1-\frac{Pe}{2}) $

McqOptions · Answer

$\frac{\phi_c-\phi_w}{\phi_E-\phi_w} = \frac{1}{2}(1+\frac{Pe}{2}) $

McqOptions · Answer

$\frac{\phi_c-\phi_w}{\phi_E-\phi_w} = \frac{1}{2}(\frac{Pe}{2}-1) $

McqOptions · Answer

$\frac{\phi_c-\phi_w}{\phi_E-\phi_w} = (\frac{Pe}{4}) $
