Oil (kinemaic viscosity, voil = 1.0 $\times$ 10–5 m2/s) flows through a pipe of 0.5 m diameter with velocity of 10 m/s. Water (Kinematic Viscosity, vw = 0.89 $\times$ 10–6 m2/s) is flowing through a model pipe of diameter 20 mm. for satisfying the dynamic similarity, the velocity of water (in m/s) is _____________
