Problem No. 1 (5 points) A piezometer and a pitot tube are tapped into a horizontal water pipe, as shown in figure, to measure the pressures at points (1) and (2). For the indicated water column heights, determine the pressure pi and the velocity V at point (1) and the pressure p2 and the velocity V at point (2). Assume the water density is equal to 10 kg/m, the atmospheric pressure is 105 N/m, and the gravity acceleration g = 9.8 m/s. Water h = 12 cm h = 7 cm h = 3 cm Stagnation point V
