A cylindrical silo with $3.0 \mathrm{~m}$ diameter and height to diameter ratio of 5: 1 is filled with 60 metric ton wheat grains having bulk density of $725 \mathrm{~kg} \mathrm{~m}^{-3}$. The coefficient of friction between grain and silo wall is 0.42 and the ratio of lateral pressure to vertical pressure is 0.5 . The vertical pressure at the bottom of silo in $\mathbf{k P a}$ (round off to 2 decimal places) is ______________. [use $1 \mathrm{kgf}=9.81 \mathrm{~N}]$
