7. Water flows through a pipe of diameter 1.08m at a velocity of
2m/s. If someone puts a nozzle on the end of the pipe, reducing the
diameter to 0.35m, at what speed will the water exit the pipe?.

10. A pipe with a radius of 50 cm has water flowing at 5 m/s. If
water goes into a new pipe with radius 33 cm, how much will the
pressure decrease?

11. A large dam has a hole that is 56 meters from the top. If
the water in the reservoir is depending at a rate of 0.33 m/s, how
fast is the water exiting the hole?

12. A hand pumped water gun is held at height of 1.3 m above the
ground. The water lands 8.4 meters away. What is the exit velocity
of the stream? What is the gauge pressure of the gun’s reservoir,
assuming the velocity of the water is zero and doesn’t change
height before leaving the reservoir?
