Q1: A water pipe narrows from a radius of
(R1=5 cm) to a radius of (R2=2 cm. If the
speed of the water in the wide part of the
pipe is (2 m/s). What is the speed of the water
?at the narrow part

Q6: Water enters a horizontal pipe with a
rectangular cross section at a speed of 1 m/s.

the height decreases. Twenty meters from
the entrance, the height is half of what it is at
the entrance. If the water pressure at the
entrance is 3000 Pa, what is the pressure 20
?m downstream
