12.2 Bernoulli’s Equation
You can squirt water a considerably greater distance by placing your thumb over the end of a garden hose and then releasing, than by leaving it completely uncovered. Explain how this works.
The reason behind this can be explained by continuity property of incompressible fluid . For an incompressible fluid in a pipe, the continuity equation says volume of fluid crossing any cross section of pipe per unit time is constant. Hence if area of cross section is less velocity of fluid will be high and vice-versa.Hence you can squirt water a considerably greater distance by placing your thumb over the end of a garden hose and then releasing, than by leaving it completely uncovered as in the forst case area of cross section of garden hose is reduced than the later case.

PRACTICE IT Use the worked example above to help you solve this problem. A water hose 2.15 cm in diameter is used by a gardener to fill a 31.0-liter bucket. (One liter = 1,000 cm.) The gardener notices that it takes 1.00 min to fill the bucket. A nozzle with an opening of cross-sectional area 0.500 cmis then attached to the hose. The nozzle is held so that water is projected horizontally from a point 1.00 m above the ground....

LEARN MORE REMARKS It's interesting that the motion of fluids can be treated with the same kinematics equations as individual objects. QUESTION By what factor would the range be changed if the flow rate were doubled? ***** * * ****** PRACTICE IT Use the worked example above to help you solve this problem. A water hose 2.20 cm in diameter is used by a gardener to fill a 33.0-liter bucket. (One liter = 1,000 cm?.) The gardener notices that it...
Can you drive your car in such a way that the distance it covers is (a) greater than, (b) equal to, or (c) less than the magnitude of its displacement? In each case, give an example if your answer is yes, explain why not if your answer is no. drawing would be helpful
1. Try this, if you haven't before: Place your finger tightly over the top of the straw, and lift the straw up out of the water. You should find that the water stays in the straw. a. What is the net force on the water in the straw? b. Draw a free body diagram for a system that is the water. c. Is the gas pressure inside the straw, between the liquid and your finger, greater than, less than, or...
is tap water better than bottled water? how can you explain your answer
Can you please solve each step by step?
Thanks
2.) It is well known that you can trap liquid in a drinking straw by placing the tip of your finger over the top while the straw is in the liquid and then lifting the straw out. The density of water is 1.0 g/cm3, and assume atmospheric pressure is 101.3 kPa. When the straw has been removed from the liquid (a) What is the net force on the cylinder of trapped...
The Green Thumb Water Sprinkler Company was founded in 1948 by
Arthur Green, an entrepreneur with an avid interest in home
gardening. Today the successful company, known as Arthur Green,
Inc., is run by Arthur’s descendants. Among other things Arthur
Green produces a line of high-quality sprinklers targeted at
upper-income hobbyists. The company’s products are considered very
“retro” in design and are seen by customers as unique and harkening
back to an earlier time. To reinforce this image company catalogs...
Day in and day out, you probably depend on many different sorts of complex technological tools and innovations. Luckily, the modern world has embraced some sense of user-focused design in many of its products, so you should not need an engineering degree to operate a microwave oven or create a spreadsheet on your laptop. The most popular technology “just works” and does not require you to toil over hundreds of densely-packed pages of a user manual. Imagine sitting comfortably at...
Problem 1 to 6: You are driving your brand new Mustang on a straight highway. Suddenly you felt a strong desire to check physics while driving and so you checked the gauge: It indicates that the speed is 80 kilometers per hour. You enjoyed driving for another hour while checking speeds. At the end of speeding up period of one hour, you read your car's speed as 160 kilometer per hour. Then suddenly you saw red and blue flashing light...
