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?
