A piezometer and a Pitot tube are tapped into a 4-cm-diameter horizontal water pipe, and the height of the water columns are measured to be 26 cm in the piezometer and 32 cm in the Pitot tube (both measured from the top surface of the pipe). Determine the velocity at the center of the pipe. The velocity at the center is m/s.
