Question

A $1$ $\text{mm}$ thick cylindrical tube, $100$ $\text{mm}$ in diameter, is orthogonally turned such that the entire wall thickness of the tube is cut in a single pass. The axial feed of the tool is $1$ $m/\text{minute}$ and the specific cutting energy $\left(u\right)$ of the tube material is $6 J / mm^{3}$. Neglect contribution of feed force towards power. The power required to carry out this operation is _______________ $kW$ (round off to one decimal place).
