PROBLEM 5: The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown. Determine the gage pressure of air in the tank if h1 = 0.4 m, h2 = 0.6 m, and h3 = 0.8 m. Take the densities of water, oil, and mercury to be 1000, 850 , and 13,600 kg/m^3, respectively.
In Eq. 7.14, it is assumed that the density of the animal is greater than the density of the fluid in which it is submerged. If the situation is reversed, the immersed animal tends to rise to the surface, and it must expend energy to keep itself below the surface. How is Eq. 7.14 modified for this case?
