In an apartment building, water is traveling up inside a pipethat has a constant cross-sectional area.
(A.) Which of the following statements aboutthis 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 headpipe is 5 liters per minute. What is the speed of the water exitingthe pipe? _______ m/s
(C.) The shower head above is in a fourth floorapartment, 15 meters above the main pipe in the building basement.The main pipe in the basement is 10 cm in diameter. What must thewater speed be in the main pipe? ______ m/s
(D.) A fourth floor apartment is 15 metersabove the main pipe in the building basement. The flow from a 2 cmdiameter shower head pipe is 5 liters per minute. The main pipe inthe 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 flowon the fourth floor? Take g to be 9.8 N/kg and atmospheric pressureto be 101.3 kPa.
_______ kPa
