A water pipe is inclined 34.0° below the horizontal. The radius of the pipe at the upper end is 2.00 cm. If the gauge pressure at a point at the upper end is 0.117 atm, what is the gauge pressure at a point 3.20 m downstream, where the pipe has narrowed to a 1.00 cm radius? The flow rate is 20.0π cm3/s.
