Since the same water level is reached in both vessels, it is very easy to set the same level even over long distances where simple spirit levels cannot be used. The water level can be read off the scales. Two vessels are each provided with a scale and connected to each other by a flexible tube filled with water. The fact that identical water levels form in vessels that are connected to each other is technically used in so-called water level devices. If this were the case, currents would form and there would be no equilibrium. Thus, there cannot be two different hydrostatic pressures at a certain depth.
The fact that identical hydrostatic pressures form in the equilibrium state is also shown by the fact that pressures in liquids act equally in all directions. It was shown that the hydrostatic pressure p h depends only on the depth hbelow the liquid surface besides the density ϱ of the liquid and the gravitational acceleration g: The main objective of this example is to illustrate the steps involved in simulation of a water tower using Ansys Fluent and to visualize the pressure contour on the tower.In the article Pressure in liquids, the formation of hydrostatic pressure and its calculation was explained in detail. In this example, the pressure distribution along the depth of the water tower will be visualized using Ansys Fluent simulation. As a result of high-pressure water entering the pumps, less work is done by the pumps to deliver water. The water pumps used to deliver water to different locations use the gravitational force from the tower to provide high-pressure water. Most water tanks are positioned at about 50 meters from the ground to deliver water to different locations using smaller or fewer pumps. The tank will supply water during peak hours of the day when the demand is less, water will be pumped into the tank. Clean, treated water is stored in large tanks, which most commonly will supply water to an entire city or town. The two primary functions of a water tower are to store and pressurize water for distribution.
