What is polymerization example? A polymer is a large single chain-like molecule in which the repeating units derived from small molecules called monomers are bound together. The process by which monomers are transformed into a polymer is called polymerisation. For example ethylene polymerizes to form polyethylene. What are the two types of polymerization? There are […]
What is fin effectiveness?
What is fin effectiveness? The fin temperature effectiveness or fin efficiency is defined as the ratio of the actual heat transfer rate through the fin base divided by the maximum possible heat transfer rate through the fin base, which can be obtained if the entire fin is at base temperature (i.e., its material thermal conductivity […]
