Difference Between Piston and Plunger
Piston vs Plunger Piston pumps and plunger pumps are two types of positive displacement pumps working based on a reciprocating mechanism. They are the most commonly used type of reciprocating pumps to transport gasses or liquids at a very low to 150 MPa pressure. What is a Piston Pump? Operation of the piston pump […]
Difference Between Compressor and Blower
Compressor vs Blower Compressors and blowers are machines used to transport gasses, and change their fluid properties, especially the properties related to pressure. In many industrial applications, these devices can be found because air or some other gas is used as the working fluid, and it needs to be transported from one component to […]
Difference Between Search and Research
Search vs Research Search and research are two words in English language that are confusing for students learning English. This is because of the similarities between the two words as both contain search in them.

Difference Between Subjunctive and Indicative
Subjunctive vs Indicative Subjunctive and indicative are two of the three moods a verb can have. There are many languages of the world (mostly Indo-European) where these moods of the verb matter a lot and have to be understood before one can hope to become proficient. Thus, verbs have not just tenses but also […]
Difference Between Acronym and Initialism
Acronym vs Initialism Most of us are aware of the concept of acronyms as we hear so many of them in our daily lives. We use these acronyms while writing and quickly recognize them because of our experience. While writing date, we write Jan for January and Oct for October. This is called abbreviation […]
