Wаter оf density 1000 kg/m³ flоws аt а speed оf 3.0 m/s through a section of pipe of radius 0.040 m. The pipe bends upward to 0.25 m above its original height and tapers to a radius of 0.020 m, as shown in the figure above. If the water pressure is in the lower part of the pipe, the water pressure in the upper part of the pipe is most nearly:
