Relative humidity is the amount of water vapor present in the air compared to the maximum amount the air can hold at a specific temperature.
Relative humidity is expressed as a percentage.
It is an important factor in weather forecasting and climate studies.
High relative humidity can make the air feel warmer than it actually is, while low relative humidity can make the air feel cooler.
For example, if the relative humidit...
Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
Centrifugal pumps use a rotating impeller to increase the pressure of a fluid.
Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge.
Axial flow pumps move fluid parallel to the pump shaft.
Examples: Centrifugal pump - used in HVAC systems, Positive displacement pump - used in hydrau...

The crushed bauxite is then mixed with a hot caustic soda solution in a digester vessel
The resulting slurry is filtered to remove impurities
The filtered solution is then cooled and aluminium hydroxide is precipitated
The precipitated aluminium hydroxid...
Inputs for blast furnace include iron ore, coke, limestone, and hot air.
Iron ore is the primary input and is usually in the form of hematite or magnetite
Coke is a fuel used to heat the furnace and is made from coal
Limestone is added to remove impurities and create slag
Hot air is blown into the furnace to increase the temperature
Other inputs may include scrap metal, fluxes, and additives
