The governing equation for liquid rise in capillary tube is obtained using momentum balance. This
equation describes the dynamic of capillary rise when all parameter effects are considered. The
governing equation was normalized in a form of nonlinear ordinary equation using dimensionless
parameter. This model was solved numerically using fourth-order Rung Kutta method and were
validated by comparing it with experimental data and other theorical results. The transient time
(T*) between the present model and LWE when ω ˂ 0.25 was calculate. The result shows that
viscous force is more important than other forces after the transient time (T*), so in this time
interval LWE can be used.
