Question 1 of 10⏱ 08:00
Water moves through a pipe at 3 meters per second and then enters a nozzle whose exit diameter is half the pipe's diameter. The flow is steady and the water is treated as incompressible, so the volume passing each second stays the same. The engineer uses the continuity equation, area times speed, to find the exit speed from the nozzle in meters per second.
