Question
The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in the figure. Determine the gauge pressure of the air in the tank if h = 0.2 m, h2 = 0.3 m, and h3 = 0.46 m. Use the densities in the appendix of water at 25°C, light oil, and mercury. (20 pt)
