Fresh water is flowing at 8.73 m/s through a horizontal pipe that is many miles long, and it is 0.275 m above the ground. The pressure is 318 kPa and the radius of the pipe is 0.0416m. The pipe suddenly goes either up or down a hill (you will determine this) and then levels out so that it is horizontal again.  The pressure is 753 kPa and the water here flows at 1.56 m/s.  What is the height of the pipe at this location, and is it above or below ground level? The image below shows the general shape of the pipe.
