A U-tube open at both ends is partially filled withwater (Fig. P14.81a). Oil having a density 750 kg/m3 isthen poured into the right arm and forms a columnL 5 5.00 cm high (Fig. P14.81b). (a) Determine thedifference h in the heights of the two liquid surfaces.(b) The right arm is then shielded from any air motionwhile air is blown across the top of the left arm untilthe surfaces of the two liquids are at the same height(Fig. P14.81c). Determine the speed of the air being blown across the left arm. Take the density of air asconstant at 1.20 kg/m3.
