Two piezometers $A$ and $B$ spaced $200\text{ m}$ apart in a homogeneous sand aquifer record groundwater piezometric heads of $45.0\text{ m}$ and $43.0\text{ m}$, respectively. The hydraulic conductivity of the sand is $K = 25.0\text{ m/day}$ and the effective porosity is $n_e = 0.25$. The actual pore water seepage velocity ($v_s = \frac{K \cdot i}{n_e}$) in $\text{m/day}$ is ________ (answer in integer).
