Water with pressure of 190 kPa flows down hill through a pipe with a 3.90 cm diameter hose at a speed of 1.2 m/s. It then exits through a smaller pipe m of diameter 1.50 cm which is 5.00 m below the upper pipe. a. What is the speed of the water exiting at the lower pipe opening? b. What is the water pressure at the exit of the lower pipe. ?

Water is flowing through a horizontal pipe with diameter, D1, at
a velocity, V1, and under a pressure, P1. It enters a 900 reducing
bend (Shown in grey in Fig 2) that connects to a vertical pipe of
diameter, D2. The inlet of the bend is 50 cm above the exit of the
bend (as shown in Fig 2). Axes for positive directions of x and z
coordinates are provided. Figure 2 Side view of reducing bend from
horizontal to...
