Water is pumped at a steady uniform flow rate of $0.01 \mathrm{~m}^{3} / \mathrm{s}$ through a horizontal smooth circular pipe of $100 \mathrm{~mm}$ diameter. Given that the Reynolds number is 800 and $g$ is $9.81 \mathrm{~m} / \mathrm{s}^{2}$, the head loss (in meters, up to one decimal place) per km length due to friction would be
