Velocity will decrease.
Velocity will decrease; that means, here we will have free stream velocity. What will happen here? Here, the velocity will reduce because it is in the boundary layer. The water velocity is less at the centre and slowly increases to full value towards the boundary layer limit. So, you see, the speed of water here is less than the free stream velocity, or we can assume if you assume the ship moving in this direction V, as if its pulling a, pulling an amount of water with it. Am I clear? The pull, the, the, this, the amount of water it is be the velocity which is it is pulling the water is this velocity, is not it?
