Water enters a horizontal pipe with a rectangular cross section at a speed of 1 m/s. The width of the pipe remains constant but the height decreases. Thirty-eight meters from the entrance, the height is half of what it is at the entrance. If the water pressure at the entrance is 4100 Pa, what is the pressure 38 m downstream?
