in thermal radiations what is the difference between effective surface area and surface area of emitting body ,and how to calculate effective surface area of ang body?
sadhu said:consider a case of a hollow cylinder with one side open to outside &
external area is covered by insulating material, temperature is T
assuming perfect BB how to calculate heat lost by it in 1 sec,
E=[tex]\sigma[/tex]*T[tex]^{4}[/tex]*?
length is l, radius is r.
as i think ?=[tex]\pi[/tex]*r[tex]^{2}[/tex]
Effective surface area refers to the area of a solid object that is available for chemical reactions or interactions with other substances.
Calculating effective surface area is important because it allows scientists to determine the amount of available surface for reactions, which can impact the efficiency and effectiveness of chemical processes.
Effective surface area is typically calculated by using mathematical formulas based on the dimensions and geometry of the object, such as the surface area of a sphere or the surface area of a cube.
The shape and size of an object, as well as its surface texture, can greatly impact its effective surface area. For example, an object with a rough surface will have a larger effective surface area compared to a smooth object of the same size.
Understanding effective surface area can help in various industries, such as pharmaceuticals, materials science, and environmental science. It can aid in designing more efficient drug delivery systems, creating more effective materials, and improving pollution control methods, among others.
