A siphon pipe of diameter 250 mm contracts to a diameter of 100 mm over a vertical distance of 5 m before emptying into a river. If the pipe is full of water flowing at 0.1 m/s at the 250 mm section, what is the absolute pressure at this point, and what is the water velocity just before it vents into the river? You should assume the pipe to be frictionless and take atmospheric pressure to be 100 kPa.

A siphon pipe of diameter 250 mm contracts to a diameter of 100 mm over a vertical
distance of 5 m before emptying into a river. If the pipe is full of water flowing at 0.1
m/s at the 250 mm section, what is the absolute pressure at this point, and what is
the water velocity just before it vents into the river? You should assume the pipe to
be frictionless and take atmospheric pressure to be 100 kPa.
