On a day in which the local atmospheric pressure is 99.5 kPa, answer each of the following: (a) Calculate the column height of mercury in a mercury barometer in units of meters, feet, and inches. (b) Francis is concerned about mercury poisoning, so he builds a water barometer to replace the mercury barometer. Calculate the column height of water in the water barometer in units of meters, feet, and inches. (c) Explain why a water barometer is not very practical. (d) Ignoring the practicality issue, which of the two (mercury or water) would be more precise? Explain.

Consider a differential manometer whose ends are connected to two different pipes A andB and containing different liquids at different levels. Let us assume that the pressure at point A is more than that at point B. Oil is in pipe A whose density 800 kg/m³ shows a difference in mercury levels as 100 mm. The height of oil between center of pipe A to the mercury level in left limb is 200 mm. Methanol (relative density 0.791) is in pipe B and the height of Methanol between center of pipe B and mercury level in the right limb is 5 cm. Calculate the difference in pressures at the two points A and B.
