Types of pumps include centrifugal, positive displacement, 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 impeller shaft.

• Examples include centrifugal pumps in HVAC systems, diaphragm pumps in chemical processing, and axial

Blast furnace is a metallurgical process used to extract iron from its ore through reduction reactions.

• Iron ore, coke, and limestone are fed into the furnace

• Hot air is blown into the furnace to ignite the coke and initiate the reduction process

• The iron ore is reduced to molten iron, which is tapped off at the bottom of the furnace

• Slag, a byproduct of the process, is also tapped off and used in construction

• The process i...read more
