Analyzing a Multifluid Manometer with EES

Reconsider the multifluid manometer discussed in Example 1–7 and replotted in Fig. 1–61. Determine the air pressure in the tank using EES. Also determine what the differential fluid height h₃ would be for the same air pressure if the mercury in the last column were replaced by seawater with a density of 1030 kg/m³.

Example 1–7

Measuring Pressure with a Multifluid Manometer

The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in Fig. 1–49. The tank is located on a mountain at an altitude of 1400 m where the atmospheric pressure is 85.6 kPa. Determine the air pressure in the tank if h₁ = 0.1 m, h₂ = 0.2 m, and h₃ = 0.35 m. Take the densities of water, oil, and mercury to be 1000 kg/m³, 850 kg/m3, and 13,600 kg/m³, respectively
