You try to remove ethyl alcohol from a glass by blowing across the top of a vertical straw immersed in the ethyl alcohol. What is the minimum speed you must give the air at the top of the straw to draw ethyl alcohol upward through a height of 1.6 cm? (Note: The density of olive oil, if you need it, is 920 kg/m3.)

Mercury is poured into a tall glass. Ethyl alcohol (which does not mix with mercury) is then poured on top of the mercury until the height of the ethyl alcohol itself is 112 cm. The air pressure at the top of the ethyl alcohol is one atmosphere. What is the absolute pressure at a point that is 7.91 cm below the ethyl alcohol-mercury interface?

The mile high city of Denver, Colorado is at an altitude of 1600 m above sea-level. (a) Make the assumption that the density of air (1.2 kg/m3 ) is constant versus height to estimate the air pressure in Denver. (b) You decide to impress your Rocky Mountain friends by showing how you can use a long straw. How low does the pressure need to be in your lungs to use a straw that is 1.5 m long (assume you are...

Az water Air 1 atm 1. Your gardening hose has a hose-end feeder attached for spraying insecticide or fertilizer. It works on the Bernoulli principle, similar to the atomizer we did in class-rushing water through the hose creates a lower pressure that draws up insecticide/fertilizer through the sprayer. Data: Cross sectional area of the hose at point 1 is 5.2 cm2. Speed of the water at point I is 2.8m/s. Density of water is 1000 kg/m, Density...
