In an apartment building, water is traveling up inside a pipe that has a constant cross-sectional area.

(A.) Which of the following statements about this situation are true? Choose the two correct statements.

As the water rises¸ it slows down

As the water rises¸ its speed stays the same

As the water rises¸ the pressure drops

As the water rises¸ the pressure stays the same

(B.) The flow from a 2 cm diameter shower head pipe is 5 liters per minute. What is the speed of the water exiting the pipe? _______ m/s

(C.) The shower head above is in a fourth floor apartment, 15 meters above the main pipe in the building basement. The main pipe in the basement is 10 cm in diameter. What must the water speed be in the main pipe? ______ m/s

(D.) A fourth floor apartment is 15 meters above the main pipe in the building basement. The flow from a 2 cm diameter shower head pipe is 5 liters per minute. The main pipe in the basement is 10 cm in diameter. What must the pressure (in kPa) in the main pipe in the basement be in order to generate that flow on the fourth floor? Take g to be 9.8 N/kg and atmospheric pressure to be 101.3 kPa.
_______ kPa
