Water (density $1000 \: kg/m^3$) flows through an inclined pipe of uniform diameter. The velocity, pressure and elevation at section $\textbf{A}$ are $V_A=3.2 \: m/s, \: p_A=186 \text{kPa}$ and $z_A=24.5 \: m$, respectively and those at section $\textbf{B}$ are $V_B=3.2 \: m/s, \: p_b=260 \text{kPa}$ and $z_B=9.1 \: m$, respectively. If acceleration due to gravity is $10 \: m/s^2$ then the head lost due to friction is ________ $m$ (round off to one decimal place)
