2. The basic barometer can be used to measure the height of a building. If the barometric readings at the top and at the bottom of a building are 675 and 695 mmHg, respec- tively, determine the height of the building. Take the densi- ties of air and mercury to be 1.18 kg/m2 and 13,600 kg/mº, respectively. 3. Freshwater and seawater flowing in parallel horizon- tal pipelines are connected to each other by a double U-tube manometer, as shown in...
