A) Water moves in a pipe that has a diameter of 34 cm at 1 m/s, but then the pipe reduces to a diameter of 16 cm. Find the velocity of the water in the smaller portion of the pipe.
B) Water in a hose with an area of 186 mm2 moves at 4 m/s, but then you cover part of the opening of the hose with your finger, and the water shoots out faster at 26 m/s . Find the area of the opening between your finger and the end of the hose in mm2.
C) Water moves in a pipe from the ground up to a height of 10 m. At the bottom of the pipe the water has a velocity of 1 m/s. As the pipe goes up it reduces in diameter and at the top of the pipe it has a velocity of 14 m/s and a pressure of 280000 Pa. Find the necessary pressure at the bottom of the pipe to deliver the water to the top. (density of water = 1000 kg/m3 )

Water with pressure of 190 kPa flows down hill through a pipe with a 3.90 cm diameter hose at a speed of 1.2 m/s. It then exits through a smaller pipe m of diameter 1.50 cm which is 5.00 m below the upper pipe. a. What is the speed of the water exiting at the lower pipe opening? b. What is the water pressure at the exit of the lower pipe. ?

Water is delivered to a 4.0 cm diameter fountain head from a 6.9 cm diameter pipe that is 3.4 m below the fountain head and at a pressure of 94 kPa. The fountain head shoots the water straight up into the air. Neglect all losses. a.) What is the velocity of water coming out of the fountain head? Hint: Must use Bernoulli AND Continuity b.) What is the volume flow rate of the water through the fountain head? Hint: Q=vA

Two garden hoses of different diameter are needed to reach a flower bed. Water flows with a speed of 1.2m/s through the bottom section of a garden hose that goes up a step 20.0 cm high. The cross-sectional area of the hose at the top of the step is half that at the bottom of the step. If the water pressure is 143 kPa at the bottom of the step, what is its pressure and velocity at the top of...
