The effective area refers to the area of a surface that is actually utilized for a specific purpose, while the actual area is the total surface area of an object without taking into account any factors that may affect its use.
The measurement of effective area takes into consideration any obstructions or limitations that may affect the functionality of a surface, while the measurement of actual area does not account for these factors.
Some factors that can affect the effective area of a surface include the shape, size, and placement of the object, as well as any environmental conditions such as temperature or pressure.
Understanding the difference between effective area and actual area is important because it allows for more accurate and efficient use of resources. By knowing the effective area, one can ensure that only the necessary amount of resources and materials are used for a specific purpose.
Yes, the effective area of a surface can change depending on the conditions and factors that may affect it. For example, a surface may have a different effective area in a high-pressure environment compared to a low-pressure environment.
