Water is draining from tank A to tank B. The elevation difference between the two tanks is 10 m. The pipe connecting the two tanks has a sudden-expansion section as shown. The cross-sectional area of the pipe from A is 8 cm2, and the area of the pipe into B is 25 cm2.
Assume the head loss consists of two losses: due to the sudden-expansion section and due to flow into tank B. Find the discharge between the two tanks.
