A heat exchanger is a device used to transfer heat between two or more fluids.
Heat exchangers are used in various industries such as chemical, power, and HVAC.
They work by allowing two fluids to flow through separate channels, with heat transferring from one fluid to the other.
Common types of heat exchangers include shell and tube, plate and frame, and finned tube.
Heat exchangers can be used for heating, cooling, ...
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.
Examples include the distillation of crude oi...

Broaching is a metal cutting process that uses a toothed tool called a broach to remove material from a workpiece.
It is used for shaping internal or external surfaces, such as keyways, splines, and gears.
Broaching can be used as a finishing process to achieve tight tolerances and smooth surface finishes.
It can also...
There are two main types of IC engines: spark ignition (SI) engines and compression ignition (CI) engines.
Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly used in gasoline engines.
Compression ignition (CI) engines rely on the heat generated by compressing the air-fuel mixture to ignite it, commonly used in diesel engines.
Other types include rotary engines, two-stroke engines, a...
