where, v is the vertical component of the free stream velocity and y is the vertical distance from the surface of a solid and Re is the reynolds number.

Can someone please help me understand what this interpretation means?

Thanks in advance

My interpretation would be: if the reynolds number quadruples, v and y become approximately half as big

Often the funny O is used instead of 'is proportional to' (##\propto##) if the reasoning aims to justify ignoring certain terms. But I don't know if that is true in your context.

This is called viscous flow.In this when you go upward from a fixed surface the velocity of the layer of liquid increases.At the bottom layer velocity would be zero and at top velocity of layer would be maximum.Reynold number shows that upto a specific value of Reynold number flow would be viscous and beyond that number flow would become transit and the turbulent flow.see the images below.
