Centrifugal pump mechanism involves the conversion of mechanical energy into kinetic energy to increase the fluid's velocity and pressure.
Centrifugal pump consists of an impeller that rotates to create centrifugal force.
Fluid enters the pump through the center of the impeller and is flung outwards by centrifugal force.
The fluid gains kinetic energy and pressure as it moves through the pump.
The fluid is then discha...
Flash point is the temperature at which a substance gives off enough vapor to ignite momentarily, while fire point is the temperature at which a substance will continue to burn after ignition.
Flash point is the temperature at which a substance can ignite momentarily when exposed to an ignition source.
Fire point is the temperature at which a substance will continue to burn after ignition.
Flash point is typically lo...
A centrifugal pump works by converting mechanical energy from a motor into kinetic energy in a fluid through the rotation of an impeller.
The pump's motor spins an impeller, creating a centrifugal force that pushes the fluid towards the outer edges of the pump casing.
As the fluid moves through the pump, it gains kinetic energy and pressure, which allows it to be discharged through the pump outlet.
Centrifugal pumps ...

Vaccum distillation is a process that separates liquids based on their boiling points under reduced pressure.
Vaccum distillation is used to purify liquids with high boiling points or heat-sensitive compounds.
It involves heating the liquid in a distillation flask under reduced pressure to lower its boiling point.
The reduced pressure allows the liquid to vaporize at a lower temperature, preventing thermal degradatio...
A venturi is a device used to measure the flow rate of a fluid by creating a pressure difference.
A venturi consists of a narrow throat section and wider inlet and outlet sections.
As fluid flows through the venturi, its velocity increases in the narrow throat, causing a decrease in pressure.
The pressure difference is measured and used to calculate the flow rate of the fluid.
Venturis are commonly used in industries ...
Mass transfer is the movement of substances from one place to another due to a concentration gradient.
Mass transfer involves the transfer of mass or substances, such as molecules or ions, from one phase to another.
It occurs due to a difference in concentration or partial pressure between the two phases.
Examples of mass transfer include the diffusion of gases in air, the movement of solutes in a liquid, and the eva...
Centrifugal pumps are devices that use centrifugal force to move fluids through a system.
Centrifugal pumps are commonly used in industries such as oil and gas, water treatment, and chemical processing.
They consist of an impeller that rotates to create centrifugal force, which pushes the fluid towards the pump outlet.
The fluid enters the pump through the suction inlet and is accelerated by the impeller.
The kinetic ...
Reflux is the process of condensing and returning the vapors that rise from the distillation process back into the distillation flask.
Reflux helps to improve the efficiency of the distillation process by preventing the loss of volatile components.
It is achieved by using a condenser to cool the vapors and return them to the distillation flask.
Reflux is commonly used in the production of high-purity chemicals and fu...

I appeared for an interview in Nov 2024, where I was asked the following questions.
- Q1. Type of Mechanical seal
- Ans.
Mechanical seals prevent fluid leakage in rotating equipment, enhancing efficiency and safety in various applications.
Types include single seals, double seals, and cartridge seals.
Single seals are commonly used in pumps and compressors.
Double seals provide extra protection against leakage, often used in hazardous environments.
Cartridge seals simplify installation and maintenance, suitable for various industrial applica...
- Q2. Part of seal
- Ans.
A seal can refer to a marine animal or an emblem used for authentication. Both have distinct characteristics.
Seals are marine mammals known for their streamlined bodies and playful behavior.
The term 'seal' can also refer to a stamp or emblem used to authenticate documents.
Examples of seals include the harbor seal and the elephant seal.
In legal contexts, a seal signifies the authenticity of a document.
