Plz solve it plz solve this

Dear Student,
Given , density =1000 kg/m³ , length = diameter = L = 2r = 2 x 2x 10^-2 m/s, Speed, v = 2 m/s.
$$\begin{gathered} Reynold\text{'}s number=\frac{\rho VL}{\eta } \\ =\frac{1000\times 2\times \left(2\times 2\times {10}^{-2}\right)}{8\times {10}^{-2}} \\ =1000 \end{gathered}$$
Regards
