We learned that a column of mercury in a barometer is around 760 mm in height. We also learned that a water barometer would have to be over 10 m tall. What would be the height of a column of isopropyl alcohol if it were used in a barometer? the density of isopropyl alcohol is 785 kg/m3 (meters cubed).

wheel to stop? 2. A meterstick weighing 1.2 N is supported horizontally by two fulcra positioned at x1 = 30 cm and x2 = 90 cm. Assume that the stick's center of gravity is at its exact center (i.e., Xcg = 50 cm). Draw a diagram of the three forces acting on the meterstick. What are the magnitudes of the upward forces exerted by the two fulcra on the stick? 3....

The column of mercury in a barometer stands 70.0cm high. How tall would the barometer have to be if the mercury were replaced by water? (the density of mercury is 1.36x10^4kg/m^3)

A mercury barometer reads 744 mm on the roof of a building and 761 mm on the ground. Assuming a constant value of 1.29 kg/m3 for the density of air, determine the height of the building.
(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury?
(a) How high in meters must a column of water be to exert a pressure equal to that of a 760-mm column of mercury? The density of water is 1.0 g/mL whereas that of mercury is 13.6 g/mL (b) What is the pressure, in atmospheres, on the body of a diver if he or she is 39 ft below the surface of the water when atmospheric pressure at the surface is 0.97 atm?

While mercury is toxic it is far more convenient to use in barometers since the height of the liquid will be minimal as the following calculation will illustrate. 1 mL of mercury (13.6 g/mL) placed into a cylindrical glass column is 1 mm tall. How tall would a column of water (1 g/mL be if ti were the same mass as the mercury column? Use equations for pressure to solve.

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...
