What will happen is that the stream diameter will become smaller to account for the faster velocity. If the water were a bar of elastic material this would be the same as stretching it. It's mass flow is the same, it just elongates as it becomes faster. By the time it reaches the bottom of the vertical pipe the stream will not have a diameter of A.

Get PriceFluid Flow Velocity Profiles. Not all fluid particles travel at the same velocity within a pipe. The shape of the velocity curve (the velocity profile across any given section of the pipe) depends upon whether the flow islaminar or turbulent. If the flow in a pipe is laminar, the velocity distribution at a .

Hence the pressure loss per unit length is the same everywhere, except that in your case of a vertical pipe, you need to add the effect of gravity (which I believe you have separately accounted for already).
