## Homework Statement

At a certain point in a pipeline, the velocity is 1 m/s and the gauge pressure is 3 x 10

^{5}N/m

^{2}. Find the gauge pressure at a second point in the line 20 m lower than the first if the cross-section at the second point is one half that at the first. The liquid in the pipe is water.

## Homework Equations
