You try to remove olive oil from a glass by blowing across the top of a vertical straw immersed in the olive oil. What is the minimum speed you must give the air at the top of the straw to draw olive oil upward through a height of 1.2 cm? (Note: The density of olive oil, if you need it, is 920 kg/m3.)

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.)
On a bet, you try to remove water from a glass by blowing across the top of a vertical straw immersed in the water. What is the minimum speed you must give the air at the top to the straw to draw water upward through a height of 1.6 cm.
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...
shown perpendia looking straight down into the top of the glass. A light beam is shown perpendicular to the surface hace of a film of olive oil floating on top of water inside the glass (see nghtness at a wavelength of 500 nm in the air. The indexes of refraction, n drawing below). When the student looks down at the film the student sees green light side view that has a maximum a for the materials are given below Light...
A 4.00 cm x 4.00 cm x 4.00 cm cube of density 920 kg/m3 is floating at rest at the top of a beaker of cross sectional area 100 cm2 with 500 mL of water in it. 500 mL of oil of density 900 kg/m3 is added to the top of the beaker, and the cube is observed to float completely submerged, unevenly straddling the boundary between the oil and water. a. Draw a picture showing the beaker, layers of...
A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
A raft is made of 11 logs lashed together. Each is 38.0 cm in
diameter and has a length of 7.00 m. How many people (whole number)...
12. (-/2 points) DETAILS SERCP11 9.A.P.088. MY NOTES ASK YOUR TEACHER A U-tube open at both ends is partially filled with water (Figure (a)). Oil (p = 750 kg/m?) is then poured into the right arm and forms a column L = 4.43 cm high (Figure (b)). P Shield U Water Oil (a) Determine the difference h in the heights of the two liquid surfaces.

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...
