Question: Water is flowing smoothly through a closed pipe system. At one point the speed of the water is 3.0 m/s, while at another point 1.0

Water is flowing smoothly through a closed pipe system. At one point the speed of the water is 3.0 m/s, while at another point 1.0 m higher the speed is 4.0 m/s.

A. If the pressure is 20 KPA at the lower point, what is the pressure at the upper point?

B. What would be the pressure at the upper point, if the water stops flowing in the pipe, and the pressure at the lower point is decreased to 18 KPA?
