Velocity difference between high point and low point

[stberry]

Dear all,

I need help.

Given:
1. There are two points. One of them is 1 meter higher than the other.
2. Water goes from the high point to the low point by gravity.

I want to know whether the velocity of the low point is constant or not regardless of the length of two points.

Any help would be appreciated.

Sorry,
I modified some contents a little bit.

Points have no length.

Do you mean the distance between the two points?

Are the points connected? If so, how? With a pipe, or with a trough, or a flat surface?

So far we can only say, at steady state, its constant.

a pound goes in a pound goes out unless its compressing. so mass in = mass out for water. The density isn't changing unless there is a huge pressure/temperature change, so mass/density = velocity is the same on each end.

Not necessarily. We don't know if its not open channel flow and he could have a decreasing head reservoir at the high point, or an increasing head reservoir at the low point, (or v/v) making for a nonsteady state solution.
