Condensers are devices used to condense a substance from its gaseous to its liquid state.
There are two main types of condensers: air-cooled and water-cooled.
Air-cooled condensers use air as the cooling medium, while water-cooled condensers use water.
Examples of air-cooled condensers include car radiators and air conditioning units.
Examples of water-cooled condensers include cooling towers and refrigeration systems.

Azeotropic distillation is a process used to separate azeotropes, which are mixtures of liquids that boil at a constant temperature.
Azeotropic distillation involves adding a third component to the mixture to break the azeotrope.
The third component forms a new azeotrope with one of the original components, which can then be separated from the other component.
This process is commonly used in the production of ethanol, wh...
Reynolds number is a dimensionless quantity used to predict fluid flow patterns and turbulence.
Reynolds number is calculated as the ratio of inertial forces to viscous forces in a fluid.
It is used to determine whether a fluid flow is laminar or turbulent.
The range of Reynolds number for laminar flow is less than 2300, while for turbulent flow it is greater than 4000.
In between these values, the flow may be transitional...

Distillation is a process of separating components of a liquid mixture based on their different boiling points.
Distillation involves heating a liquid mixture to vaporize the more volatile components.
The vapor is then cooled and condensed back into a liquid, separating it from the less volatile components.
The separated components can have different boiling points, allowing for purification or concentration of specific s...
Heat transfer is the process of energy transfer between objects or substances due to temperature differences.
Heat transfer can occur through conduction, convection, and radiation.
Conduction is the transfer of heat through direct contact between objects or substances.
Convection is the transfer of heat through the movement of fluids or gases.
Radiation is the transfer of heat through electromagnetic waves.
Examples of heat...

Various solvents are used in production engineering depending on the specific application, such as water, alcohols, hydrocarbons, and acids.
Water is commonly used as a solvent for cleaning and rinsing processes.
Alcohols like ethanol are used for dissolving oils, resins, and waxes.
Hydrocarbons such as hexane are used for extracting oils and fats.
Acids like sulfuric acid are used for pickling and cleaning metal surfaces.
I applied via Walk-in and was interviewed before Apr 2021. There were 3 interview rounds.
The manufacturing process of semi-finished products involves several steps including casting, rolling, forging, and machining.
The process starts with melting the raw material in a furnace.
The molten metal is then poured into a mold to create the desired shape.
The semi-finished product is then subjected to rolling, forging, or extrusion to improve its mechanical properties.
After that, the product is machined to achieve ...
Challenge test is required to ensure the reliability and accuracy of compression machines and frequency.
Challenge test helps to identify any potential issues with the compression machine and frequency.
It ensures that the machine is producing accurate and consistent results.
The test involves subjecting the machine to extreme conditions to see how it performs.
For example, a compression machine may be tested by compressin...
There are various types of tooling used in production, including cutting, forming, and assembly tools.
Cutting tools: used to remove material from a workpiece, such as drills, saws, and milling cutters
Forming tools: used to shape a workpiece without removing material, such as dies and molds
Assembly tools: used to join multiple components together, such as screws, bolts, and rivets
Other types of tooling include measuring
