## Homework Statement

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 1.5 cm?

(Note: The density of olive oil, if you need it is 920 kg per cubic meter.)

## Homework Equations

P1 + .5*density*v1^2 + density*g*y1 = P2 + .5*density*v2^2 + density*g*y2

## The Attempt at a Solution

P1 + .5*density*v1^2 + density*g*y1 = P2 + .5*density*v2^2 + density*g*y2

P1 = .5*density*v2^2 + density*g*y2

V2 = 14.83 m/s

V2 is close, but not right; I'm not sure how to find P2. What do I need to do different?
