A pump is a mechanical device used to move fluids from one place to another. There are various types of pumps.
Pumps are used in various industries such as oil and gas, water treatment, and manufacturing.
Types of pumps include centrifugal pumps, reciprocating pumps, and rotary pumps.
Centrifugal pumps are commonly used for low viscosity fluids, while reciprocating pumps are suitable for high-pressure applications.
Example...
A cooling tower is a device that removes heat from a process or building by transferring it to the atmosphere.
Cooling towers are commonly used in industrial processes and HVAC systems.
They work by evaporating a small portion of the water being circulated, which removes heat from the remaining water.
The cooled water is then recirculated back into the system.
Cooling towers can be classified into different types, such as ...
