Fluid Mechanic Dynamics
Fluid mechanics is a part of mechanical engineering that explains the state and the movement of fluids such as water. Fluid mechanic concepts are used to create various objects for household or industrial purposes. One of the common systems that use the application of fluid mechanic dynamics is a water fountain system. Water fountains often are used as attractions in public places. Further, fountains are used in gardens to keep the land moist for crop growth and development. In both cases, the fountain system employs similar fluid mechanisms where water is forced to move to a higher level through the application of pressure. The weak molecules of water make it hard for the fluid to resist pressure, thus making it possible for the water to create the needed shapes. A fountain has a reservoir from which water is sprayed and stored to create a closed circuit. The water is sprayed in the air to create a waterfall effect. To help create enough pressure, a pump is fixed in the reservoir under the water. An impellor in the pump draws water and distributes it through centrifugal force. The water is then delivered to the fountainhead and sprayed into the air through a fine nozzle or falls down on the outer part of the structure. The released water falls back to the fountain and down to the reservoir, thus forming a closed circuit.
A fountain uses several hydraulic concepts to create the beautiful scenery that people enjoy. The water moves from a larger vessel, the reservoir to a narrow pipe, which creates the needed pressure to form the necessary shapes. In addition, the water in the reservoir moves in circular motions due to the spinning of the pump impellor; therefore, different hydraulic concepts apply to create a new direction into the pipe and out the fountain nozzle. Pipe flow, fluid control circuits, and pumps are some of the concepts involved in the fountain system. The volume of water dispensed does not change regardless of the vessels in which it passes. Therefore, the same volume of water pumped into the pipe in the reservoir is released to the finer pipes in the fountain nozzle. The change in the sizes of the shapes creates the necessary pressure needed to spray water in the air at a very high speed. At the reservoir, there are fluid control circuits that ensure that the volumes of water remain constant to enhance the process. The pump is fitted with a spinning impellor that takes water in at a high speed and forces it out via the pipes.
Pipe flow, fluid control circuits and the pump help to create the needed pressure to pump water into the air in a fountain. The key issue in creating a fountain is the ability to control the volume of the water released and the volume of the water retained in the reservoir. The three hydraulic concepts ensure that the water is not too much to break the pipes nor too little to exert low pressure. The pipe flow limits the amount of water being sprayed into the air while increasing the speed of the water at the same time. The pump on the other hand ensures that the water leaves the reservoir at a speed high enough to guarantee ideal spraying while the controls ensure that the right volumes are maintained in the pipes and at the reservoir.
