## Homework Statement

You have a pipe and 4 points on it. Points 1 and 2 are at h = 0, with point 1 having a smaller cross-section than point 2. Next, point 3 has the same cross-section as point 2, but the pipe goes up, so that h > 0. Point 4 is level with point 3, but has an even larger cross-section.

Rate the points according to:

1. The volume flow rate,

2. The flow speed.

3. The water pressure.

## Homework Equations

The Bernoulli equation and the continuity equation.

## The Attempt at a Solution

It's a been some weeks since we've covered this, and I just wanted to make sure I have the right idea.

1. The same everywhere.

2. Point 1 > points 2 and 3 > point 4. The difference in heights doesn't influence flow speed, if the area is the same, right?

3. Points 3 and 4 > points 1 and 2, because they are at the same height.

Is this correct? Thanks in advance.

Oh, and I know this one is really easy, but sometimes I just get sort of a mental block with getting some stuff I had already done, I don't know why. It's like I need to get past it and then everything flows smoothly again
