Question

5.) Most homes have an outdoor faucet to which they can attach a standard 3/4 inch (diameter) garden hose. When it is attached to a standard garden hose, Fred's outdoor faucet delivers water at a rate of 7.6 feet/sec. In order to water a larger area, Fred splits his standard hose into three 1/2 inch lines. If the water is distributed through all of the 1/2 inch hoses equally, what is the volume flow output of each of the 1/2 inch lines.

6.) Oil is flowing through a pipeline at a speed of 1.44 m/s. If the diameter of the pipe is 0.86 m, what is the volumetric flow rate?

7.) The air above an airplane wing moves faster than the air below it. A certain airplane wing is 35 meters by 3.1 meters. The wind speed above the wing is 260 m/s and below it is 223 m/s. Assuming that the elevation and air density (1.29 kg/m3) are approximately the same at these two points, what is the pressure difference caused by the wind speeds?

8.) A fountain is designed to spray a column of water 9 m into the air. What minimum velocity must the water have exiting the nozzle in order to reach the desired water height?

9A.) A hand-pumped water gun is held at height of 1.3 m above the ground. The water stream lands 8.7 meters away. What is the exit velocity of the stream?

9B.) 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?

10.) A large dam has a hole that is 42 meters from the top. If the water in the reservoir is descending at a rate of 0.69 m/s, how fast is the water exiting the hole?
