Positive Displacement Pump: Types, Working, Advantages & Applications Explained

Leave a Comment / Fluid Mechanics /

A positive displacement pump (PDP) is a type of pump that moves fluid by trapping a fixed volume and forcing (displacing) it into the discharge pipe. Unlike centrifugal pumps, it delivers a constant flow rate regardless of pressure variations, making it highly reliable for precise fluid handling. These pumps are widely used in industries such as oil […]

Pump: Definition, Types, Working Principles, and Applications

Leave a Comment / Fluid Mechanics /

Pumps are one of the most essential mechanical devices used across industries and daily life. Simply put, a pump moves fluids (liquids or gases) from one place to another by converting mechanical energy into hydraulic energy. Whether it’s lifting water from a well, circulating coolant in engines, or delivering fuel in automobiles, pumps play a

Reciprocating Pump – Main Parts, Types, Working, Advantages, Disadvantages & Applications

Leave a Comment / Fluid Mechanics /

A reciprocating pump is a type of positive displacement pump widely used where high pressure and precise fluid delivery are required. Unlike centrifugal pumps, it works by moving fluid using a back-and-forth (reciprocating) motion of a piston or plunger inside a cylinder. This mechanism makes it highly efficient for handling low flow rates at high

What is Surface Tension? Definition, Formula, Examples & Applications

Leave a Comment / Fluid Mechanics /

Surface tension is a fundamental property of liquids that explains why small insects can walk on water, why droplets form spherical shapes, and why liquids resist external force at their surface. In simple terms, surface tension is the tendency of a liquid surface to behave like a stretched elastic membrane. This phenomenon occurs due to

What is Cavitaion? How It Occurs, Effects, and Prevention

Leave a Comment / Fluid Mechanics /

Cavitation is a critical phenomenon in fluid mechanics that directly impacts the performance and lifespan of machines like pumps, turbines, and propellers. It occurs when the pressure of a liquid falls below its vapor pressure, causing the formation of vapor bubbles that later collapse violently. This seemingly small event can generate powerful shockwaves capable of

Centrifugal Pump – Working Principle, Main Parts, and Applications

Leave a Comment / Fluid Mechanics /

A centrifugal pump is one of the most widely used mechanical devices for transporting fluids in industries, homes, and infrastructure systems. It works by converting mechanical energy into hydraulic energy using centrifugal force generated by a rotating impeller. These pumps are essential in applications such as water supply systems, irrigation, chemical processing, and power plants.

Pelton Turbine: Working, Main Parts, Applications (Complete Guide)

Leave a Comment / Fluid Mechanics /

A Pelton turbine is a type of impulse turbine used to generate power from high-head water sources. It is widely used in hydroelectric power plants where water is available at a high elevation but with relatively low flow rates. Unlike reaction turbines, the Pelton turbine converts the entire kinetic energy of a high-speed water jet
