A U-tube open at both ends is partially filled with water. Oil having a density of 750 kg/m^3 is then poured into the right arm and forms a column 5.00 cm in height.
The right arm is shielded from any air motion while air is blown across the top of the left arm until the surfaces of the two liquids are at the same height. Determine the speed of the air being blown across the left arm. (The density of air is 1.29 kg/m^3.)

You need to use your knowledge of the Bernoulli effect, which states that a moving fluid has a pressure contribution of 0.5*rho*v^2, where rho is the density of the moving fluid and v is its velocity. You also need to take into account the pressure effect of the change in fluid column height.
