What are the affinity laws?
Acts on affinity are a set of rules to describe the interconnected relations between speed, flow, power and pressure observed on fans, turbines and similar devices. These rules are critical for installing heating and cooling, who have to choose products suitable for their needs and calibrate correctly. They are also useful in designing other systems where turbines, fans and pumps can be used. These laws are published in texts for this sector and usually learn and discuss training. As the engine slows down, the flow of air or other turbine materials will also slow down. To increase the flow it is necessary to increase speed. The amount of pressure is also subject to affinity laws; The pressure will be equal to the engine speed, the second. The faster the engine is, the more energy it requires. Affinity laws Discuss The fact that the power needed to start the fan or similar device is equal to the cube of engine speed. Other topics to which the laws on affinity laws,They are the diameter of the impeller and the effect that can have strength, strength and other performance problems. These rules are consistent across many types of systems, reflecting basic physics for fans.
Installation staff of systems subject to affinity laws must think about the use of the system and install the appropriate equipment and support infrastructure. For example, a high performance drawing must be accommodated with a corresponding energy source. The installation program is considering the maximum voltage on the system and is responsible for the design, such as in the case of air conditioning in a very hot climate, where users can convert the system into maximum setting in thermal wool. Failure to consider maximum voltage can lead to problems such as breakdown system under high demand.
Acts on affinities can also be important in research and development. Scientists work with flow and air pressure in research andExperimenting to explore topics such as aerodynamics. They must design repeatable and quantifiable experiments in order to report the results accurately. Part of this process includes fully describing the conditions of the experiment, such as a vortex created in an experimental chamber with fans to see how the aircraft works in wind conditions.
