If it takes $\displaystyle 5$ minutes to fill a $\displaystyle 15$ litre bucket from a water tap of diameter $\displaystyle \frac{2}{\sqrt{\pi}} \mathrm{~cm}$ then the Reynolds number for the flow is (density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$ and viscosity of water $\displaystyle =10^{-3}$ Pa.s) close to :
Official answer
(1)
$\displaystyle 5500$
