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 small jet airplane has a total wing area of 62.5 m2 and a mass of 7.03 104 kg. (a) If this jet is in horizontal flight, determine the pressure difference between the lower and upper surfaces of the wings. (b) When the speed of air traveling over the wing is 237 m/s, determine the speed of air under the wing. Use 1.29 kg/m3 as the density of air.
