Power plant cycle is a series of processes that convert fuel into electricity.

• Fuel is burned to produce heat

• Heat is used to boil water and create steam

• Steam turns a turbine which generates electricity

• Excess heat is released into the environment

• Water is cooled and recycled in the system

Casting methods are processes used to create metal objects by pouring molten metal into a mold.

• Sand casting: uses sand molds to create the shape of the object

• Investment casting: uses wax patterns that are melted away to create the mold

• Die casting: uses metal molds to create complex shapes with high accuracy

• Permanent mold casting: uses reusable molds made of metal

• Centrifugal casting: rotates the mold to distribute the m

Batch production is a manufacturing process where products are made in groups or batches, rather than individually.

• Products are produced in specified quantities at a time

• Each batch goes through the whole production process together

• Common in industries like food processing, pharmaceuticals, and automotive manufacturing

Supercritical stage of steam refers to a state where it exhibits properties of both liquid and gas.

• Occurs at temperatures and pressures above the critical point

• Density and viscosity are similar to liquids, while diffusivity and compressibility are similar to gases

• No distinct boundary between liquid and gas phases

• Used in power plants for more efficient energy generation
