Water from a pipe is coming at a rate of $\displaystyle 100$ liters per minute. If the radius of the pipe is $\displaystyle 5$ cm, the Reynolds number for the flow is of the order of : (density of water = $\displaystyle 1000 \mathrm{~kg} / \mathrm{m}^3$, coefficient of viscosity of water $\displaystyle =1 \mathrm{mPa} \mathrm{s}$ )
Official answer
(1)
$\displaystyle 10^4$
