A Pitot tube can be used to determine the velocity of air flow by measuring the difference between the total pressure and the static pressure (Fig. P14.49). If the fluid in the tube is mercury, density PHg = 13 600 kg/m3, and Δh = 5.00 cm, find the speed of air flow. (Assume that the air is stagnant at point A, and take Pair = 1.25 kg/m3.)
