A timber pile of length $8 \mathrm{~m}$ and diameter $0.2 \mathrm{~m}$ is driven with a $20 \mathrm{kN}$ drop hammer, falling freely from a height of $1.5 \mathrm{~m}$. The total penetration of the pile in the last 5 blows is $40 \mathrm{~mm}$. Use the Engineering News Record expression. Assume a factor of safety of 6 and empirical factor (allowing reduction in the theoretical set, due to energy losses) of $2.5 \mathrm{~cm}$. The safe load carrying capacity of the pile (in $k N,$ round off to 2 decimal places) is
