It is proposed to drive H-piles up to a depth of $7$ m at a construction site. The average surface area of the H-pile is $3 \: m^2$ per meter length. The soil at the site is homogeneous sand, having an effective friction angle of $32^{\circ}$. The ground water table (GWT) is at a depth of $2$ m below the ground surface. The unit weights of the soil above and below GWT are $16 \: kN/m^3$ and $19 \: kN/m^3$, respectively. Assume the earth pressure coefficient, $K=1.0$, and the angle of wall friction, $\delta=23^{\circ}$. The total axial frictional resistance (in kN, up to one decimal place) mobilized on the pile against the driving is _____________
