The picture shows a section of pipe within a closed system (not open at the ends). Water (density 1000 kg/m³) flows from left to right in the system. At point A, the pipe diameter is 60 cm, the speed of the water is 24 m/s, and the pressure is 1.3 atm. At point B, the pipe diameter is 2.4 m. The height difference h is 3.5m.

The picture shows a section of pipe within a closed system (not
open at the ends). Water (density 1000 kg/m³) flows from left to right
in the system. At point A, the pipe diameter is 60 cm, the speed of
the water is 24 m/s, and the pressure is 1.3 atm. At point B, the pipe
diameter is 2.4 m. The height difference h is 3.5m.
What is the pressure at point B? (Hint, use continuity to determine
the speed at point B, then use the Bernoulli equation.)
