A U-tube open at both ends is partially filled with water (Fig. P15.67a). Oil having a density of 750 kg/m3Ā is then poured into the right arm and forms a columnĀ LĀ = 5.00 cm high (Fig. P15.67b). (a) Determine the differenceĀ hĀ in the heights of the two liquid surfaces. (b) The right arm is then 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 (Fig. P15.67c). Determine the speed of the air being blown across the left arm. Take the density of air as constant at 1.20 kg/m3.
