Water is flowing at $100$ $\mathrm{litres}/ \mathrm{min}$ through a pipe with a diameter of $5$ $\mathrm{cm}$. Assume the coefficient of viscosity of water to be $0.001$ $\mathrm{Pa}.\mathrm{s}$ and the density to be $1000 \mathrm{~kg} / \mathrm{m}^{3}$. The Reynolds number for this flow is $\_\_\_\_$ (Round off to nearest integer)
